The formation of an ionic compound involves the transfer of electrons. The removal of one or more electrons from a metal is a process that _____ energy, whereas the addition of one or more electrons to a nonmetal _____ energy.
The formation of an ionic compound involves the transfer of electrons. The removal of one or more electrons from a metal is a process that absorbs energy, whereas the addition of one or more electrons to a nonmetal releases energy.
The formation of ionic compounds occurs between two kinds of atoms having a large electronegativity difference (Δx ≥ 0.7) e.g metals (like those in group IA and IIA) and non-metals(like those in groups VIA and VIIA). The formation of an ionic bond involves the transfer of electron(s) from the less electronegative atom (metal) to the more electronegative atom (non-metal) such that the two kinds of atoms now have a completely filled outer shell like the noble gas.
