Number of orbitals in a sub shell is given by the formula 

B) 11, Sodium

C) a → ii, b → iv, c → i, d → iii

C) a—ii, b→iii, c→iv, d→i

A) Both statements are correct

C) a→iii, b→i, c→iv, d→ii

Correct option is  B) 2l + 1

Correct option is  B) 4l + 2

Correct option is  B) n2 

For N-shell principal quantum number n = 4  ∴ Total number of orbitals in N-shell = n2 = 42 = 16.  The total number of subshells in N-shell = n  = 4. The four...

Correct option is  D) 3,3
