Question

is bond formation only takes place between similar atoms?​

Answer 1

Explanation:

They are formed only between similar atoms because of sharing of electrons. The main reason is that similar atoms have same elctronegativity difference, which is important for the formation of covalant bonds, and this happens only when a bond is formed between similar atoms.

Answer 2

Answer:-

An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions. Ionic bonds are formed between a cation, which is usually a metal, and an anion, which is usually a nonmetal. A covalent bond involves a pair of electrons being shared between atoms.
