What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.

Front

Back

Chlorine (Cl) has a greater electronegativity than Aluminum (Al).

Front

What is atomic radius?

Back

Atomic radius is the distance from the nucleus of an atom to the outermost shell of electrons.
