Question

If l=3 then type of subshell and number of orbitals is

Answer 1

l=0 corresponds to s subshell

l=1 to p subshell

l=2 to d subshell

and l=3 to f subshell, f subshell has 2l+1 i.e. 7 orbitals in it.

Answer 2

Answer: Type of subshell will be p and number of orbitals will be 7.

Explanation:

Principle Quantum Numbers : It describes the size of the orbital and the energy level. It is represented by n. Where, n = 1,2,3,4....

Azimuthal Quantum Number : It describes the shape of the orbital. It is represented as 'l'. The value of l ranges from 0 to (n-1). For l = 0,1,2,3... the orbitals are s, p, d, f...

Magnetic Quantum Number : It describes the orientation of the orbitals. It is represented as $m_l$. The value of this quantum number ranges from $(-l\text{ to }+l)$. When l = 2, the value of $m_l$ will be -2, -1, 0, +1, +2.

For l=3 , the subshell would be f and for l= 3, possible values of m are +3, +2, +1, 0 , -1 , -2 and -3. Thus number of orbitals will be 7.
