Question

An atom has three full orbitals in its second energy level.

How many electrons are present in the second energy level of the atom?

9

12

6

3

Answer 1

6

Step-by-step explanation:

The maximum number of electrons in the orbitals of sub-levels are given as:

for s-sublevel we have two electrons and one orbital

p-sublevel we have six electrons and three orbitals

d-sublevel we have ten electrons and five orbitals

f- sublevel we have fourteen electrons and seven orbitals

The second energy level is represented by the p-sub-level and it will accommodate 6 electrons.
