Why do atoms bond? Describe examples of the two ways elements complete their valence shell through bonding

kindly see Explanation

Explanation:

Atoms bond in other to achieve a stable valence electron shell. Through bonding, atoms with incomplete valency in the outer shell may accept, lose or share electrons with another atom in other to achieve a stable outer shell or configuration.

Ionic bonding:

Ionic or electrovalent bonding simply occurs when atoms accept or lose electrons in their outer shell in other to achieve stability. Elements that require 1 atom to achieve stability accepts from elements which requires losing 1 atom in other to achieve a stable outer shell.

Example is Sodium chloride (NaCl) sodium loses one atom, which chlorine accepts and both achieve a stable outer shell.

Covalent bonding simply refers to electron sharing between atoms. Instead of losing or accepting, the atoms bond by sharing electron to achieve stability. Such is the bonding between Hydrogen and Oxygen in the formation of H2O, oxygen requires two electrons to attain stability, each hydrogen atom requires one each to attain stability, through sharing oxygen attains two more electrons, one each from the hygrogen atoms and the oxygen atom also shares one electron with each hydrogen atom. Then all the atoms atoms stability.

1.) Atoms bond in order to gain more stability.

2.) They can complete their valence by sharing (taking and giving) electrons for 1.)
