Salt compounds are composed of ions that form a tightly packed and ordered network, which is called a crystal lattice. It is held together by electrostatic forces known as ionic bonding. Ionic bonding refers to the chemical bond between two oppositely charged ions - a cation and an anion. This type of bond forms when there is a large electronegativity difference between two atoms.
