Detailed explanation-1: -If atoms have similar electronegativities (the same affinity for electrons), covalent bonds are most likely to occur. Because both atoms have the same affinity for electrons and neither has a tendency to donate them, they share electrons in order to achieve octet configuration and become more stable.

Detailed explanation-2: -The two types of chemical bonds that atoms can form to achieve stability are called ionic bonds and covalent bonds. In ionic bonds, atoms donate or receive electrons to achieve stability. In covalent bonds, atoms share electrons to achieve stability.

Detailed explanation-3: -An ionic bond is formed by the complete transfer of some electrons from one atom to another. The atom losing one or more electrons becomes a cation-a positively charged ion. The atom gaining one or more electron becomes an anion-a negatively charged ion.

Detailed explanation-4: -Stable configuration They have two or eight electrons in their valence shell. They do not gain, lose or share electrons.
