Their general electronic configuration is listed as--
For s orbital → ns [1-2] where n can have values like 1,2,3,...
For p orbital → ns2 p [1-6] where n can have values like 1,2,3,...
For d orbital → [n-1]d[1-10] ns1or 2 where n can take values 1 less than the above values
For f orbital (n - 2) f1-14 (n - 1) d0-1 ns2 where n can take values 2 less that the values u give for s:
