All forms of chemical (ionic or otherwise) involve only the valence band electrons. These electrons reside in the outermost s orbital and outermost 3 p orbitals.
the outermost electrons.
Look at the atoms involved in the bond. Then look at the electronegativity values of the atoms involved. The stronger the en value of the atoms the stronger the bond is and the more "ionic" the bond is.
Different charges
when a metal forms bond with a non metal the bond is an ionic bond.
A chemical bond that may be ionic where the atoms bonded together are charged or covalent where electrons are shared. The nature of the bond depends on the relative electronegativity of the atoms involved. An example of an ionic bond is in sodium chloride. An example of a covalent bond is one between carbon and hydrogen for example in a hydrocarbon. When an element atom bonds to another atom of the same elemnt then that bond is covalent, eg O2, N2, H2, S8.

Electrical attractions between atoms form chemical bonds.
Ions of opposite charges are involved in ionic bonding where the metal atoms form metallic bonds.
