Compounds composed of the atoms of nonmetals are not likely to have ionic bonds.
Covalent bonds usually form between two nonmetals/
Water is a covalent compound, so ionic compounds are more likely to dissolve in water.
These are the nonmetals.
It's ionic if it is bonded with hydrogen or other metals, and it's covalent if with other nonmetals, but since bromine is a halogen, it is most likely to form ionic compounds.
Chlorine, Oxygen, and Sulfer. (nonmetals)
Molecule. A nonmetal to nonmetal covalent bond. Electronegativity is not variant enough among the nonmetals to form ionic bonds.
