Metallic and Nonmetallic Character | Chemistry for Non …
Metallic character refers to the level of reactivity of a metal. Metals tend to lose electrons in chemical reactions, as indied by their low ionization energies. Within a compound, metal atoms have relatively low attraction for electrons, as indied by their low electronegativities.

What causes ions to form ionic bonds? - A Plus Topper
The non-metal atoms accept the electrons donated by the metal atoms to achieve a stable noble gas electron arrangement. Thus, negatively-charged ions are formed. The positively-charged ions and negatively-charged ions are then attracted to each other by strong electrostatic forces which are closely-packed in an orderly manner in a crystal lattice, forming an ionic compound.
