subshell 2s: _2__ shell 1: _2__ one 4f orbital: __2_ subshell 5p: _6__
11. For an atom of 13Al, write its full electron configuration: 1s_
Draw a full orbital diagram (e¯s as arrows in boxes with labels):
Count the unpaired e¯s in the orbital diagram __1___
Is 13Al atom diamagnetic or paramagnetic? (mark one) paramagnetic (unpaired electron)
Write four quantum numbers n, l, ml, ms for all its valence electrons:
1s2 2s2 2p6 3s2 3p1
↑↓ ↑↓ ↑↓↑↓↑↓ ↑↓ ↑
for 3s2: n=3, l=0, ml = 0, ms = +1/2 -1/2
for 3p1 n=3, l=1, ml=1,0,-1, ms = +1/2
