How many electrons in an atom have the following auantum numbers ? (i) n=4, m_(s)=-1/2 (ii) n=3, l=0. |

Answer» Solution :(i) TOTAL ELECTRONS in `n=4` are `2 n^(2)`, i.e., `2xx4^(2)=32`. Half of them, i.e., 16 electrons have `m_(s)=-1/2`. (II) `n=3, l=0` means 3s orbital which can have 2 electrons. |
