Ionic bonds do not have valence electrons; rather, they form between atoms by electron transfer where one atom gives up electrons (cations) and the other gains electrons (anions). The resulting ions are held together by electrostatic forces, not by sharing electrons as in covalent bonds.
One calcium atom will form an ionic bond with one sulfur atom, since calcium will donate its two valence electrons to sulfur in order to achieve a stable electron configuration.
A phosphorus atom typically gains three electrons to achieve a stable electron configuration in an ionic bond. This allows it to attain a full outer valence shell with eight electrons, similar to the electron configuration of a noble gas.
let's use the ions Cl- and H+ forming HCl, hydrochloric acid, chlorine has 7 valence electrons and hydrogen has one, so when they form an ionic bond the valence shell is filled with 8 electrons. i hope that answered your question, I'm a chem major in college so i should know this stuff in and out but only a freshman so i don't lol ~Mau

Three electrons are transferred to form a bond between aluminum and sulfur because aluminum has 3 valence electrons while sulfur has 6 valence electrons. Aluminum donates its 3 electrons to sulfur, completing the octet for both atoms and forming an ionic bond.
To form an ionic bond, calcium (which has 2 valence electrons) can donate its two electrons to sulfur (which requires 2 additional electrons to complete its valence shell). Therefore, one calcium atom can bond with one sulfur atom to form an ionic compound. Thus, only one calcium atom is needed to form an ionic bond with one sulfur atom.
One chlorine atom will form an ionic bond with one magnesium atom. The magnesium will donate its two valence electrons to the chlorine atom, filling both of their valence electron shells.
Two fluorine atoms are needed to form an ionic bond with calcium, as each fluorine atom will contribute one electron to satisfy calcium's two valence electrons.

One chlorine atom is needed to form an ionic bond with one magnesium atom because magnesium can donate its two valence electrons to chlorine, which requires one more electron to complete its octet.
