How are ionic bonds formed?
An ionic bond is formed when one atom accepts or donates one or more of its valence electrons to another atom. A covalent bond is formed when atoms share valence electrons. The atoms do not always share the electrons equally, so a polar covalent bond may be the result. When electrons are shared by two metallic atoms a metallic bond may be formed.

What are Chemical Bonds?
All the atoms complete their duplet or octet by acquiring the nearest noble gas electronic configuration to attain stability. It can be achieved by the formation of chemical bonds between atoms. Do you know how?
Why do atoms share only their outermost electrons?
This is because the atoms share only their outermost electron so that each atom gets the stable electron arrangement of inert gas. The number of electrons shared between the atoms is called its covalency. A covalent bond can also be formed between two atoms of the same non-metal.
What is the name of the compound that contains ionic bonds?
The compounds containing ionic bonds are called ionic compounds, as ions are their constituent particles. The number of electrons lost or gained by the atom during the bond formation is called its electrovalency.
Why are ionic compounds called ionic compounds?
The compounds formed by ionic bonds are called ionic compounds because they are made up of oppositely charged ions. Let us take an example showing the formation of ionic compounds. Formation of Potassium Chloride, KCl. Potassium reacts with chlorine to form ionic compounds potassium chloride ( KCl).
How do atoms form chemical bonds?
An atom can form chemical bonds in three ways, (a) By losing one or more electrons to another atom. (b) By gaining one or more electrons from another atom. (c) By sharing one or more electrons with another atom. The two modes of attaining the electronic configuration of the nearest noble gas give rise to four types of bonds.
What is chemical bonding?
Chemical bonding is the process of uniting two or more atoms by the redistribution of electrons, resulting in each atom achieving a stable electronic state.
Which chemical bond is the most powerful?
The covalent link is the most powerful chemical bond. Due to the mutual sharing of electrons, they developed between two atoms. Water is a classic example of a covalent bond because both hydrogen and oxygen atoms exchange electrons.
What is the holding pair of electrons?
The holding pair of electrons are the electrons that unite iotas in a covalent bond. The organisation of a distinct grouping of particles termed an atom—the smallest component of a compound that holds the synthetic character of that compound—is made possible by these holding pairs of electrons.
How many valence electrons does a hydrogen atom have?
For Example, One Hydrogen atom has one valence electron and one Chlorine atom has seven valence electrons in the HCL molecule. By sharing one electron, a single bond is established between hydrogen and chlorine in this situation.
Why do covalent bonds form when electrons are shared unequally?
When electrons are shared unequally, this type of covalent bond forms because the electronegativity of the joining atoms vary. For more electronegative atoms, the pull for electrons will be stronger. The electronegative difference between the atoms is more than zero but less than 2.0. As a result, the shared pair of electrons of that atom will be closer together.
How do atoms achieve security?
To achieve security, each of the atoms completes their duplet or octet by obtaining the nearest tolerable gas electronic arrangement. It’s usually performed by the formation of composite connections between particles.

Why do atoms bond?
Atoms bond so that their outer shells are full of electrons and they become stable, like noble gases. Shells are what electrons organise themselves into around the nucleus - the inside shell can have 2 electrons, and after that they hold 8, excluding transition metals and really big atoms.
What happens when metals bond?
Metallic bonds occur only in metals. The extra electrons in metal atoms are dropped, which makes the metal into a positive ion. The extra electrons become a sea of electrons, which is negative. Positive metals stick to negative electrons, and form a large metallic lattice structure. The free electrons are what conducts electricity through metals.
What is covalent bond?
Covalent bonds are where two atoms share electrons. The orbitals that electrons sit in overlap between one atom and the next, which satisfies both of them and makes them stable. The two (exclusively non-metal) atoms then can't easily move away from each other - they are like blood brothers.
What is an ionic bond?
Ionic bonds are more like blood donations. A metal atom gives electrons to a non-metal atom. Electrons are negatively charged, which means the non-metal becomes more negative and the metal becomes more positive. Like North and South on a magnet, the two ions (charged atoms) then stick together.
What is the strong attraction between closely packed positive metal ions and a'sea' of delocal?
3: Metallic Bonding :It is the strong attraction between closely packed positive metal ions and a 'sea' of delocalised electrons.An example is any metal like Zinc Iron etc
Types of chemical bond
Covalent bond . It occurs when non-metallic atoms of similar (usually high) electronegativities come together to share electrons from their last orbit to form a stable chemical compound.
Sea of electrons
The phenomenon that occurs between metallic atoms of the same type that are subjected to metallic bonds to each other is called “sea of electrons” . It can be seen as if atomic nuclei were immersed in a sea of their electrons.
Breaking chemical bonds
In electrolysis, hydrogen and oxygen are separated from water with electricity.
Hydrogen bonds
A hydrogen bridge is the union of an electronegative atom with a hydrogen atom that is, in turn, covalently bonded to another electronegative atom, forming a “bridge” between two atoms that could not normally join.
Examples of compounds with covalent bonds
Covalent bonding is extremely common in the world of organic chemistry . For example, it is present in substances such as:
Origin of the concept
Walther Kossel proposed a theory in which a total transfer of electrons occurred.
Ionic bond
Ionic bonding involves a transfer of an electron, so one atom gains an electron while one atom loses an electron. One of the resulting ions carries a negative charge (anion), and the other ion carries a positive charge (cation). Because opposite charges attract, the atoms bond together to form a molecule.
Covalent bond
The most common bond in organic molecules, a covalent bond involves the sharing of electrons between two atoms. The pair of shared electrons forms a new orbit that extends around the nuclei of both atoms, producing a molecule. There are two secondary types of covalent bonds that are relevant to biology — polar bonds and hydrogen bonds.
Polar bond
Two atoms connected by a covalent bond may exert different attractions for the electrons in the bond, producing an unevenly distributed charge. The result is known as a polar bond, an intermediate case between ionic and covalent bonding, with one end of the molecule slightly negatively charged and the other end slightly positively charged.
Hydrogen bond
Because they’re polarized, two adjacent H 2 O (water) molecules can form a linkage known as a hydrogen bond, where the (electropositive) hydrogen atom of one H 2 O molecule is electrostatically attracted to the (electronegative) oxygen atom of an adjacent water molecule.
What are the different types of chemical bonds?
There exist four primary types of chemical bonds, as listed below: Ionic bonds, also known as electrovalent bonds. Covalent bonds, also known as molecular bonds. Polar covalent bonds, also known as polar bonds. Hydrogen bonds, often abbreviated to H-bonds.
What type of bonding occurs when two atoms share electrons with each other?
Covalent Bonding. When two atoms share electrons with each other in order to obtain stable electron configurations, the resulting chemical bond is known as a covalent bond. This type of chemical bonding is often found in organic compounds (compounds containing carbon).
How do ionic bonds form?
Ionic bonds are formed when one atom (or molecule) transfers at least one electron to another atom/molecule. When this electron transfer occurs, the electron donating species develops a positive charge, and the electron accepting species develops a negative charge.
How are molecules formed?
Molecules are formed when two or more atoms participate in chemical bonding. The stability of a molecule is dependent on the strength of the chemical bonds holding the atoms together – the stronger the chemical bond, the greater the stability of the resulting molecule.
Which type of bonding is attracted to the neighboring atoms holding a partially negative charge?
Here, the hydrogen atom develops a partially positive charge and is attracted to the neighboring atoms holding a partially negative charge. Another important type of chemical bonding is the coordinate covalent bond (also known as the dative bond), which can be observed in many coordination compounds. These bonds involve the donation and acceptance ...
What is polar covalent bonding?
Polar Covalent Bonding. In these chemical bonds, the electrons are unequally shared between two atoms. The atom with greater electronegativity pulls the shared pair of electrons closer to itself, gaining a partially negative charge. On the other hand, the atom with lower electronegativity gains a partially positive charge.
