central atoms

Postby jocelyntzeng » Tue Oct 30, 2018 9:47 pm

is the central atom the element with the lowest ionization energy or the lowest electronegativity?

Hello,
the central atom is usually the atom with the lowest ionization energy.

There is an exception with hydrogen because it will never be the central atom

Ionization energy and electronegativity follow the same trends on the periodic table, so it doesn't matter which one you use to determine the central atom. It should be the least electronegative and the one with the lowest ionization energy.

Usually (maybe always??) the atom with the lower ionization energy will also have the lower electronegativity so I guess the answer would be both

It should be the least electronegative atom, except Hydrogen.

ionization energy and electronegativity do follow the same trends so technically you could use either. Using electronegativity makes more sense to me because if something was extremely electronegative it is not likely to want to share a lot of electrons therefore will not be in the middle

The atom with the lowest electronegativity is usually in the center. Electronegativity increases as you go up and right through the periodic table.

Are there any exceptions to the rule that the central atom is the one with the lowest ionization energy?
