What Is the Difference Between an Ionic and Covalent Chemical Bond

A molecule or compound is made when two or more atoms form a chemical bond, linking them together. The two types of bonds are ionic bonds and covalent bonds. In an ionic bond, the atoms are bound together by the attraction between oppositely-charged ions. For example, sodium and chloride form an ionic bond, to make NaCl, or table salt. In a covalent bond, the atoms are bound by shared electrons. If the electron is shared equally between the atoms forming a covalent bond, then the bond is said to be nonpolar. Usually, an electron is more attracted to one atom than to another, forming a polar covalent bond. For example, the atoms in water, H2O, are held together by polar covalent bonds.

It is the difference between electronegativity
1.7-4.0 is ionic
0.3-1.7 is polar covalent
0.0 to 0.3 is non polar covalent
Also in ionic bond it steals electrons and between metals and nonmetals. In covalent bonds they share electrons.

Ionic bonds are between a metal and a non-metal. A covalent bond connects two non-metals. There are some more specific differences like covalent bonds share electrons when bonded while ionic don't.

covalent is a SHARING of electrons

ionic is a TRABSFER of one or more electrons from one atom to another like NaCl is Na+ CL-

Covalent=SHARING of electrons
Ionic=STEALING of electrons
Covalent=nonmetal-nonmetal
Ionic-metal-nonmetal
