Answer

Brief Explanations:

Atomic mass is determined by the sum of protons and neutrons in the nucleus as electrons have negligible mass compared to them. Electronegativity is the ability of an atom to attract electrons towards itself in a chemical - bond.

Answer:

The sum of protons and neutrons in the nucleus To attract electrons while forming a chemical bond
