Question

write set of all 4 quantum number for 3p2.
or
n,l,m & s value for 3p2 .

Answer 1

the main quantum number is \(n=3\)
the angular-momentum \(l\), quantum number is \(l=1\)
the possible values of the magnetic quantum number are: \(-1,0,1\), in general, we have:
\(-l,-l+1,...0,...l-1,l\)
finally such orbital contains two electrons, so the spin quantum number has the subsequent two values:
\(-1/2\) and \(+1/2\)
please note that the symbol \(3p^2\), tells us that the interested orbital, is occupied by \(2\) electrons
