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.
