Introduction
Atoms combine with each other forming molecules through chemical bonds, Ionic bond produces compounds molecules only and doesn’t produce elements molecules because the ionic bond arises between two different atoms, The covalent bond produces elements molecules because it arises between two atoms for one nonmetallic element, The covalent bond produces compounds molecules because it arises between two atoms for two different nonmetallic elements.

Ex . Water atom 
The ionic bond is a type of a chemical bond that is formed as a result of a combination between a positive ion for an atom of a metallic element and a negative ion for an atom of a nonmetallic element to form a molecule of an ionic compound.
How is an ionic bond formed?!
Ionic bond arises due to the combination between a metallic element with a nonmetallic element, A metal atom loses the outermost electron and changes into a positive ion, A nonmetal atom gains the electrons lost from a metal atom and changes into a negative ion, A strong electrical (electrostatic) attraction between positive and negative ions occurs due to their difference in electric charge resulting in the ionic bond.
M → M+ + e−
X + e− → X−
M+ + X− → M+X−
The ionic bond is a chemical bond resulting from the electric attraction between a positive ion and a negative ion.

The ionic bond is a chemical bond resulting from the electric attraction between a positive ion and a negative ion.
Examples
Formation of a sodium chloride (table salt) molecule [NaCl]: A sodium (metal) atom loses one electron and changes into a positive ion (Na+), A chlorine (nonmetal) atom gain this electron (which is lost by a sodium atom) and changes into a negative ion (Cl−), A strong ionic bond is formed due to the electric attraction between a positive sodium ion (Na+) and a negative chloride ion (Cl−) forming an ionic molecule of sodium chloride (NaCl).
Formation of a magnesium oxide molecule [MgO]: A magnesium (metal) atom loses 2 electrons and changes into a positive ion (Mg+2), An oxygen (nonmetal) atom gains 2 electrons (which are lost by magnesium atom) and changes into a negative ion (O−2), A strong ionic bond is formed due to the electric attraction between a positive magnesium ion (Mg+2) and a negative oxygen ion (O−2) forming an ionic molecule of magnesium oxide (MgO).
