Question

The 3 in 4p3 represents:

Answer 1

Answer: b. the number of electrons

Explanation: $4p^3$

1. 4 is the principal quantum number which describes the size of the orbital. It is represented by n.

2. The electrons are present in p sub shell also called as azimuthal quantum Number: This quantum number describes the shape of the orbital. It is represented as 'l'. The value of l ranges from 0 to (n-1). For p orbital, l=1.

3. The p subshell contains 3 electrons.

Answer 2

B) the number of electrons
