Question

Why is electronegativity high if frontier rbital energy is low?

Answer 1

Electronegativity is a measure of how strongly atoms attract bonding electrons to themselves.

Its symbol is the Greek letter chi: χ

The higher the electronegativity, the greater an atom's attraction for electrons.

Below is a periodic table of electronegativity: the lighter the shade of green, the higher the electronegativity. Gray means no value is known.
