Which statement best explains why BeO contains a stronger ionic bond than NaCl? The atoms in BeO are larger than the atoms in NaCl so the bond will be stronger.    BeO is made up of a metal and a nonmetal so it has a stronger bond.    The atoms in BeO have a greater charge than in NaCl so the bond will be stronger.    BeO has a total of solid so it has a stronger bond.
