Boron
Boron is a chemical element with the symbol B and atomic number 5. Produced entirely by cosmic ray spallation and supernovae and not by stellar nucleosynthesis, it is a low-abundance element in the Solar system and in the Earth's crust. Boron is concentrated on Earth by the water-solubility of it…

For detailed information on transition and inner transition metals, read the main articles on Transition metals on periodic table and Inner transition metals on periodic table.
Why is group 13 less reactive?
Reactions and Compounds of the Heavier Group 13 Elements The halides of the heavier metals (In and Tl) are less reactive with water because of their lower charge-to-radius ratio. Instead of forming hydroxides, they dissolve to form the hydrated metal complex ions: [M(H 2O) 6] 3+.

The group 13 elements never react with hydrogen because the valency of hydrogen is one and that of the boron family is three. The trihalides of group 13 elements are strong Lewis acids because they have the tendency to form compounds with electron-pair donors, the Lewis bases.

Is boron reactive or stable?
Boron is a poor conductor of electricity, and is fairly non-reactive, although it is water soluble. The most common uses for boron-containing compounds includes a bleach for clothing, a swimming pool disinfectant and to produce green flames.
Are boron metals reactive?
Aluminium and gallium oxides are amphoteric in nature. Whereas indium and thallium are basic in nature. Reactivity towards acids and alkalis: Boron is unreactive when comes in contact with acids and alkalis at moderate temperatures.
What is the difference between group 3 and group 13?
Answer: Boron and Aluminium are present in Group 13 of the modern periodic table. Group 13 (IUPAC System) can also be referred to as Group IIIA. Logically, Boron and Aluminum can't be placed alongwith elements such as Yttrium as they don't exhibit properties of a transition metal.
Is group 13 metal or nonmetal?
Although group 13 includes aluminum, the most abundant metal on Earth, none of these elements was known until the early 19th century because they are never found in nature in their free state.
Why is group 13 called the boron group?
Group 13 of the periodic table is also called the boron group because boron (B) is the first element at the top of the group (see Figure below). Boron is also the only metalloid in this group. The other four elements in the group—aluminum (Al), gallium (Ga), indium (In), and thallium (Tl)—are all metals.
What charge does group 13 have?
If you look at the periodic table, you will find the metals in groups (from one to 16). Group one is composed of metals that have a +1 charge, while all the metals in groups 2,3,4,5,6,7,8,9,10,11,12, and 16 have a charge +2. Then, metals in groups thirteen and fifteen have a charge of +3.
Is boron a metal or nonmetal or metalloid?
Boron is classified as a metalloid, having properties of both metals and nonmetals: it and conducts electricity at high temperatures; but at room temperature, is it an insulator.
Why are the elements in the bottom two rows of the periodic table included in group 3?
The elements in the two bottom rows of the periodic table are also included in these groups. They are placed in the two separate rows at the bottom because they show few different properties. Actually, the elements in the bottom rows are the extension of group 3 only. So they are included in group 3. But as these elements have few different ...

What is an example of group 18?
Example of group 18. All the elements of group 18 are chemically inert (that means they do not easily react with other elements). And all the elements of group 18 have a complete octet (that means they have 8 electrons in their outer shell).

You can effortlessly find every single detail about the elements from this single Interactive Periodic table.
What is the reactivity of an element?
Reactivity of Elements of the Periodic Table. Reactivity is a measure of how easily an element will combine with other elements to form compounds. Some elements are unreactive and need energy putting in others will react spontaneously and easily.
Why do some elements react spontaneously?
Some elements are unreactive and need energy putting in others will react spontaneously and easily. The size of the nucleus determines the chemical reactivity of the element due to its ability to hold onto electrons and attract electrons. Patterns of reactivity vary depending on the size of the nucleus, the number of electrons and the number ...
Which element is unreactive?
Most of the elements in the boron group show increasing reactivity as the elements get heavier in atomic mass and higher in atomic number. Boron, the first element in the group, is generally unreactive with many elements except at high temperatures, although it is capable of forming many compounds with hydrogen, sometimes called boranes. The simplest borane is diborane, or B 2 H 6. Another example is B 10 H 14 .

The boron group are the chemical elements in group 13 of the periodic table, comprising boron (B), aluminium (Al), gallium (Ga), indium (In), thallium (Tl), and perhaps also the chemically uncharacterized nihonium (Nh). The elements in the boron group are characterized by having three valence electrons. These elements have also been referred ...
What are the trends in the borion group?
There are several trends that one could notice as they look at the properties of Boron group members. The Boiling Points of these elements drop from period to period, while densities tend to rise.
Who discovered thallium?
Thallium, the heaviest stable element in the boron group, was discovered by William Crookes and Claude-Auguste Lamy in 1861. Unlike gallium and indium, thallium had not been predicted by Dmitri Mendeleev, having been discovered before Mendeleev invented the periodic table.
Is fluorine a stable element?
Fluorine, the first halogen, is able to form stable compounds with every element that has been tested (except neon and helium ), and the boron group is no exception. It is even hypothesized that nihonium could form a compound with fluorine, NhF 3, before spontaneously decaying due to nihonium's radioactivity.
Which group of elements has the most inert s-pair effect?
The inert s-pair effect is significant in the group-13 elements, especially the heavier ones like thallium. This results in a variety of oxidation states. In the lighter elements, the +3 state is the most stable, but the +1 state becomes more prevalent with increasing atomic number, and is the most stable for thallium.
