Question

atomic mass is
the number of electrons in the nucleus
the number of protons in the nucleus
the sum of protons and electrons in the nucleus
the sum of protons and neutrons in the nucleus
electronegativity is the tendency of an element
to attract protons while forming a chemical bond
to attract neutrons while forming a chemical bond
to attract magnets while forming a chemical bond
to attract electrons while forming a chemical bond

Explanation:

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
