Question

Describe why chemical binding occurs. Give two examples of how bonds can form.

Answer 1

What is chemical binding?

Chemical bonding helps to joining atoms or molecules together. It is also helps molecules of the same or different substance to get together through joining to each other . Solid , liquid, or gaseous matter can exist in the nature due to chemical bonding .

How Chemical bonds are formed?

Bonds form when atoms share or transfer valence electrons. Valence electrons are the electrons in the outer energy level of an atom that may be involved in chemical interactions. Valence electrons are the basis of all chemical bonds.

There are two primary kinds of chemical bonds that keep atoms together:

1. Covalent
2. Electrovalent/ionic bonds.

Covalent bonds have atoms which share electrons in a chemical bond.

Ionic bonds are formed by the of atoms that have opposite charges

• Sodium chloride, or NaCl, is an example of an ionic bond.

• Another example of an ionic bond is found in lithium fluoride (LiF). Lithium has one electron in its outer shell, and fluorine has seven electrons in its outer shell.
