Question

For a shell of principal quantum number n = 4, there are

• A. 16 orbitals
• B. 8 subshells
• C. 18 electrons (maximum)
• D. 4 electrons with l = 3.

Answer 1

Answer: (A)

Maximum number of orbitals=$n^2=16$
Maximum number of electrons =$2n^2=32$
Number of subshells when n = 4
i.e., n = 1, 2, 3, 4 (K, L, M, N)
