Lewis Structure for NO2

Postby Meigan Wu 2E » Tue Nov 06, 2018 12:50 pm

If oxygen has a lower ionization energy than nitrogen, why is nitrogen the central atom in the NO2 Lewis Structure? Is it to maintain symmetry?

O is more electronegative than N, and you put the least electronegative in the center so that's why, but yes also it helps maintain symmetry.

It's because O is more electronegative. Also, usually when there is one of one element and multiple of another, the unique element is in the center (though not always, it's just a trend).

Nitrogen has a lower electronegativity than Oxygen so it goes in the middle.
