Question

Identify the neutral element represented by this excited-state electron configuration, then write the ground-state electron configuration for that element.

Excited State: 1s2 2s2 2p2 3s1

Element Symbol: ?

Ground State: ?
# electrons = 7 (count them) which means 7 protons which means element #7 in the periodic table.
Now write the ground state for N.
N
1s2 2s2 2p3
1S2 2S2 2P3
N (Nitrogen)
