a
The number of electron orbital shells.
b
The number of bonds that can be made.
c
The number of total electrons
d
The number of anti-electrons

a

The number of electron orbital shells.

a) The number of electron orbital shells.

The different rows on the periodic table, also known as periods, represent the number of electron orbital shells an atom has. Each row corresponds to a specific energy level or electron shell. The first row (period 1) represents the first energy level, the second row (period 2) represents the second energy level, and so on.
