Question

need help.
predict the group to which the element belongs whose unpaired electron has the following set of quantum numbers; n=3, l=1, m=0, s= +1/2

Answer 1

n=3, means it's on level 3
l=1, means it's on the p orbital, so 3p
m=0, means it's in the middle p orbital, so \(\sf 3p_y\)
s= +1/2 (means that it's the first electron there, we already knew this from the question)



This means it's electron configuration is \([Ne]3s^23p^2\) and the element is Si, group IV
