Please help me with this question and explain how to get the answers, I would like to learn how to do this on my own in the future

Give the chemical symbol for the element with the following ground-state electron configuration 2 2 Ne 3s 3p Symbol Write the quantum numbers nandt and select all possible values for m for each subshell of the element. 3s 3p n F m 2, -1, 0, +1, +2 1, 0, +1 m o 3, -2, -1, 0, +1, +2, +3 O 1, 0, +1 O 2, -1, 0, +1, +2 O 3, -2, -1, 0, +1, +2, +3

Explanation / Answer

The elemnt has 4 electron more than Ne which is true for Silicon

Symbol : Si

For 3S2:

n = 3 (it is just the number in front)

l = 0. (For s orbital, l is 0)

ml = 0 (for l=0, ml can be only 0)

For 3p2:

n = 3 (it is just the number in front)

l = 1. (For p orbital, l is 1)

ml = -1,0,+1 (for l=1, ml can be only -1,0,1)
