Why are they called transition metals?
Transition metals are placed between s−block and p−block elements in periodic table. They are termed as d-block elements. These metals are unstable and exhibit transitional behavior between s block and p block elements, hence the name transition metals.
Are transition metals highly reactive?
Compared with the alkali metals in group 1 and the alkaline Earth metals in group 2, the transition metals are much less reactive. They don't react quickly with water or oxygen, which explains why they resist corrosion. Other properties of the transition metals are unique.

Except for mercury, the transition metals have high melting points and high densities. They are good conductors of heat and electric current, and are very malleable.
Why do transition metals make good catalysts?
Transition metals are particularly good catalysts, thanks to incompletely filled d-orbitals that enable them to both donate and accept electrons from other molecules with ease.
Why are transition metals not very reactive?
A transition metal does not attain stable electron configuration of nearest noble gas by loss of one or two electrons. Hence, transition metals are less reactive and do not lose electrons as readily as alkali or alkaline earth metals.
Why are transition elements used?

What are transition elements and why are they called transition elements?
Transition elements (also known as transition metals) are elements that have partially filled d orbitals. IUPAC defines transition elements as an element having a d subshell that is partially filled with electrons, or an element that has the ability to form stable cations with an incompletely filled d orbital.
What are transition metal complexes used for?
Transition metal complexes are important in catalysis, materials synthesis, photochemistry, and biological systems. Medicinal inorganic chemistry can exploit the unique properties of metal ions for the design of new drugs. The use of metals and their salts for medicinal purposes has been present throughout history.
Why do transition metals have similar properties?
To answer your first question, there are 10 transition metals in the 3rd period and they account for the filling of the 3rd shell d orbitals (which can accommodate 10 electrons). As they all have electrons in the 3 d shell, they all have similar properties.
Why do transition metals have multiple oxidation states?
Transition metals can have multiple oxidation states because of their electrons. The transition metals have several electrons with similar energies, so one or all of them can be removed, depending the circumstances. This results in different oxidation states.
What Is a Transition Metal?
According to the IUPAC, a transition metal is any element with a partially filled d electron sub-shell. This describes groups 3 through 12 on the periodic table, although the f-block elements (lanthanides and actinides, below the main body of the periodic table) are also transition metals. The d-block elements are called transition metals, while the lanthanides and actinides are called "inner transition metals".
Why are transition metals considered a metal?
Because they possess the properties of metals, the transition elements are also known as the transition metals. These elements are very hard, with high melting points and boiling points. Moving from left to right across the periodic table, the five d orbitals become more filled. The d electrons are loosely bound, which contributes to the high electrical conductivity and malleability of the transition elements. The transition elements have low ionization energies. They exhibit a wide range of oxidation states or positively charged forms. The positive oxidation states allow transition elements to form many different ionic and partially ionic compounds. The formation of complexes causes the d orbitals to split into two energy sublevels, which enables many of the complexes to absorb specific frequencies of light. Thus, the complexes form characteristic colored solutions and compounds. Complexation reactions sometimes enhance the relatively low solubility of some compounds.
Why are transition metals called transition metals?
The elements are called "transition" metals because the English chemistry Charles Bury used the term in 1921 to describe the transition series of elements, which referred to the transition from an inner electron layer with a stable group of 8 electrons to one with 18 electrons or the transition from 18 electrons to 32.
What are the transition metals in the periodic table?
The d-block elements are called transition metals, while the lanthanides and actinides are called "inner transition metals".
What are the d electrons in transition elements?
The d electrons are loosely bound, which contributes to the high electrical conductivity and malleability of the transition elements. The transition elements have low ionization energies. They exhibit a wide range of oxidation states or positively charged forms.
What is the positive oxidation state?
The positive oxidation states allow transition elements to form many different ionic and partially ionic compounds. The formation of complexes causes the d orbitals to split into two energy sublevels, which enables many of the complexes to absorb specific frequencies of light.
Where are transition metals located?
The transition elements are located in groups IB to VIIIB of the periodic table. In other words, the transition metals are elements: Another way to view it is that the transition metals include the d-block elements, plus many people consider the f-block elements to be a special subset of transition metals.

Transition Metals Definition - The d-block elements are called transition metal. The d-block consists of the elements that are lying in between the s and p blocks. The position of this block is between groups 2 and 13 in the periodic table. It starts from the fourth period onwards. In these elements, the outermost shell contains one or two electrons in their s-orbital but the last electron enters the last but one d subshell (n-1) d. The properties of the elements of this block generally lie between the elements of s block and p block.

IUPAC defines transition elements as an element having a d subshell that is partially filled with electrons, or an element that has the ability to form stable cations with an incompletely filled d orbital.
What are the properties of transition elements?
General Properties of Transition Elements 1 These elements form coloured compounds and ions. This colour is explained by the d-d transition of electrons. 2 There is a relatively low gap in energy between the possible oxidation states of these elements. The transition elements, therefore, exhibit many oxidation states. 3 Many paramagnetic compounds are formed by these elements, because of the unpaired electrons in the d orbital. 4 A large variety of ligands can bind themselves to these elements. Due to this, a wide variety of stable complexes are formed by transition elements. 5 These elements have a large ratio of charge to the radius. 6 Transition metals tend to be hard and they have relatively high densities when compared to other elements. 7 The boiling points and the melting points of these elements are high, due to the participation of the delocalized d electrons in metallic bonding. 8 This metallic bonding of the delocalized d electrons also causes the transition elements to be good conductors of electricity.
How is ionization energy related to atomic radius?
In a way, the ionization energy of an element is closely related to its atomic radius. Atoms with smaller radii tend to have greater ionization enthalpies than those with relatively larger radii. The ionization energies of the transition metals increase while moving along the row (due to the increase in atomic number).
What is the configuration of electrons in transition elements?
The list of the first two rows of transition elements with their corresponding electronic configurations is tabulated below. It can be noted that in some of these elements, the configuration of electrons corresponds to (n-1)d 5 ns 1 or (n-1)d 10 ns 1. This is because of the stability provided by the half-filled or completely filled electron orbitals.
Why do radii decrease in transition elements?
The atomic and ionic radii of the transition elements decrease from group 3 to group 6 due to the poor shielding offered by the small number of d-electrons. Those placed between groups 7 and 10 have somewhat similar atomic radii and those placed in groups 11 and 12 have larger radii.

When are electrons removed from the valence shell?
In general, electrons are removed from the valence-shell s orbitals before they are removed from valence d orbitals when transition metals are ionized.
What is transition metal?
One definition of a transition metal, is any metal that has at least one unpaired d electron in one of their stable ions. Unpaired d electrons are more likely to participate in chemical reactions. This definition excludes scandium, since the Sc+3 ion does not have unpaired d electrons.
Why are transition metals colored?
Transition metal compounds are often highly colored, due to d to d electron transitions. They often form paramagnetic compounds because of their unpaired d electrons. In their elemental form, they often act as catalysts.
Why are they so colorful?
It is because of their unfilled d orbitals, and something called “d to d electronic transitions”. When a transition metal forms an ion, its electrons can absorb light and move between d orbitals. The d orbitals are normally degenerate, meaning they are all at the same energy level. But when a transition metal forms a complex with a ligand, such as H 2 O or NH 3, the d orbitals develop different energy levels. For example, Cu +2 is colorless, but Cu (H 2 0) 6+2 is a blue color. Depending on the energy difference between those d orbitals, different wavelengths of light will be absorbed and reflected. As expected, ions with no d-orbital electrons, like Sc +3, or a full d orbital, like Zn +2, are colorless.
