Find the number of orbitals and maximum electrons respectively present in M-shell?

Options

  1. A4,8
  2. B9,18
  3. C16,32
  4. D1,2

Correct answer

B. 9,18

Step-by-step solution

array |c|c|c|c|c| array l Symbol of Shell array & array c Value of Principal quantum number (n) array & array l Value of Azimuthal Quantum number (l) array & array l Symbol of subshell array & array l Total Number of orbitals in the subshell =2 l+1 array 3 * M & 3 * n =3 & l=0 & 3 ~s & 2 0+1=1 & & l=1 & 3 p & 2 1+1=3 & & l=2 & 3 ~d & 2 2+1=5 array Hence, the total number of orbitals =1+3+5=9 . Each orbital accommodates 2 electrons. Therefore, total number of electrons in M-Shell is 18 .
