How did Professor Lavelle say to choose the atom that belongs in the center of the Lewis Structure?

Hello, Dr. Lavelle mentioned in his lecture to choose the atom with the lowest ionization energy as the central atom.

Also, remember he said that hydrogen is never a central atom.

Can every atom have potentially 8 electrons in the Lewis Structure besides H and He?

Choose the atom with the lowest ionization energy to be the central atom; hence, hydrogen is never a central atom.

Yes, every atom can have potentially 8 valence electrons besides H and He.

The central atom is generally the atom with the lowest ionization energy, which is usually furthest away from row 17 (bc atoms in row 17 typically have the highest ionization energy)

I believe he said to choose the atom with the lowest ionization energy.

The atom with the lowest ionization energy level. Also H can never go in the middle.

Basically the atom with the lowest ionization energy since these atoms are the most likely to give up or share their electrons.

Dr. Lavelle also mentioned Li and Be in addition to H and He as never fulfilling the octet rule

The atom with the lowest ionization level is at the center of the Lewis structure. These are usually the ones on the left of the periodic table.

The center atom is most likely the one with the lowest ionization/electronization energy.

You put the one with lowest ionization level, but there are also some tricks that you can remember.

1) HS- hydrogen won’t be in the middle S will( hydrogen is never in the middle!)
2) CHO
Carbon is in the middle here (lower)
