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.
