Question

which quantity determines how two atoms bond? (1 point)
the difference in their electronegativities
the difference in the number of valence electrons
their total number of valence electrons
the sum of their electronegativities

Explanation:

Electronegativity difference determines bond type. If difference is large, ionic bond; if small, covalent bond. Valence electron number affects bonding capacity but not bond type. Sum of electronegativities is not a determining factor.

Answer:

the difference in their electronegativities
