Question

After a covalent bond has stabilized an atom, the atom will have

Answer 1

A full valence electron shell.

Answer 2

Answer: The atom will have a full valence electron shell.

Explanation:

Covalent bond is defined as the bond which is formed after the sharing of electrons takes place between the atoms. This is usually formed between two non-metals.

For Example: HCl is formed by the combination of hydrogen and chlorine atoms.

Hydrogen is the 1st element of the periodic table having electronic configuration of $1s^1$

Chlorine is the 17th element of the periodic table having electronic configuration of $1s^22s^22p^63s^22p^5$

Both the elements require 1 electron to complete their valence shell. Thus, both the elements will share electrons in order to form a stable compound of hydrogen chloride.

Hence, the atom will have a full valence electron shell.
