two atoms with an electronegativity difference of 2.1, will form a bond that is:

ionic, because electrons are shared.

ionic, because electrons are transferred.

covalent, because electrons are shared.

covalent, because electrons are transferred.

The ability of an atom to attract a pair of electrons in a chemical bond is called its electronegativity. The difference in electronegativity between two atoms determines how polar a bond will be

when a reversible reaction is occurring in both directions at the same rate; the products and reactants do not change in concentration. a chemical reaction where the compound is broken into its constituent parts.
