Answer:
Seesaw molecular geometry
Trigonal Bipyramidal electron geometry
Explanation:
You lied that was 12 points, but answer is nitrogen....bcuz Ionization energy is the minimum energy needed to remove a mole of electrons from a mole of gaseous atoms.
O has a lower 1st IE than N because O is 1s2 2s2 2p4 and N is 1s2 2s2 2p3. The 4th electron in the O atom's outer level has to pair up with one of the others, and this introduces repulsions, which makes it easier to remove.
The relevant factors are nuclear charge, atomic radius and screening by inner electrons.
Phosphorus has 5 valence electrons
