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

aaronq · Answer

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)

|dw:1405010236973:dw|

This means it's electron configuration is  $[Ne]3s^23p^2$ and the element is Si, group IV
