Answer:
The element is Aluminium. (assuming that the given quantum number set is for the valence electron of the unknown element)
Explanation:
The given quantum numbers are:
n=3 (Principal Quantum Number)
l=1 (Azimuthal Quantum Number)
m=0 (Magnetic Quantum Number)
s= -1/2 (Spin Quantum Number)
The given set of quantum numbers refer to the 3p orbital.
Assuming that this the valence electron of the element, the unkown element is Aluminium.
