Central Atom

Postby DanielaWong_2G » Sun Oct 23, 2016 9:16 pm

How do we determine what the central atom is? I know I wrote it down somewhere but I can't seem to find it. Was it the higher electronegative atom?

It is usually the atom will the least ionization energy.

The central atom is generally the least electronegative atom. The electronegativity increases across a period but decreases down a group.

Remember that the ionization energy increases across a period and decreases across a group.

So you would want to pick elements that are on the bottom left hand corner of the periodic table.

Why does the central atom need a low ionization energy?

The least electronegative atom means not a lot of energy is needed to remove an electron from the atom. This means that it is more likely to share electrons and create bonds, making it a good central atom.
