1.

The quantum numbers for the outermost electron of anelement are given below as n-2, 1-0, m = 0, s = +. Theatoms is(a) Lithium(c) Hydrogen(b) Beryllium(d) Boron

Answer»

given n =2 , l = 0 so, the orbital is 2s

and since the there is only 1 electron present having s = +1/2 so, the atom will be lithium.

option A.
