Answer 2

Answer:

The odd element out of lithium, chlorine, beryllium, and boron would be Chlorine.

Explanation:

Lithium (Z = 3), Beryllium (Z = 4), and Boron (Z = 5) are all in the second period, while Chlorine (Z = 17) is in the third period.

The second period consists of all elements with their valence electrons in the L (n = 2) shell, while the third period consists of the elements whose valence electrons are in the M (n = 3) shell.

Lithium is in the 1st group, i.e., it is an alkali metal.

Beryllium is in the 2nd group, i.e., it is an alkaline earth metal.

Boron is in the 13th group, i.e., it is a borogen.

Chlorine is in the 17th group, i.e., it is a halogen.
