Central Atom

Postby Peter Nguyen 2I » Sun Nov 04, 2018 12:46 am

Is the central atom always the one with the lower ionization energy? Are there any exceptions?

From my understanding, it's the least electronegative. I could be wrong though

The central atom is the one with the lowest ionization energy. So, for example, hydrogen is never the central atom in a Lewis structure.

Yes, the atom with the lowest ionization energy is the central atom. It is also worth it to note hydrogen will never be the central atom and typically (but not always) the first atom in the formula.
