Lewis Structures

[Emily Orozco L4]

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

[Hovik Mike Mkryan 2I]

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

[Jewelyana3A]

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

[Danny Elias Dis 1E]

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

[Rehan Chinoy 1K]

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

[Kyleigh Follis 2H]

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)

[josephperez_2C]

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

[Samantha Burmester 3H]

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

[405098546]

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

[Angela Cong 3C]

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

[Grace Diaz 3F]

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.

[Catly Do 2E]

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

[Hannah Morales 1D]

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)
