When an atom completely gives up its valence electrons to another atom, they form a bond that is considered to be:

• Purely ionic

• Partially ionic

• Polar-covalent

• Nonpolar-covalent

• Not a bond

You can estimate the degree to which a bond between two atoms is ionic or covalent by calculating the:

• distance between atoms nuclei

• difference in the atoms' electronegativities

• atoms' atomic radii

• overall atomic mass
