Full Answer

In an ionic bond, one of the atoms is a strong electron donor and the other atom is a strong electron acceptor. Halogens such as iodine are highly electronegative and take an electron from another atom to fill its outer orbital completely with eight electrons, which is a stable atomic state. Alkali metals such as sodium are strong electron donors with one outer orbital electron.This electron is quickly donated so that the metal's outer orbital also has eight electrons.
