Ions, charged atoms
When atoms become bonded through covalent, ionic, or hydrogen bonds they form molecules.
Covalent bonds form molecules where ionic bonds form ionic lattices. Hydrogen bonds are a form of intermolecular bonds which are formed with the participation of polar hydrogen atoms which are attached to either nitrogen, oxygen or fluorine.
There can be various amounts because molecules can form ionic bonds with other ions if they have opposite charges.
Atoms do not form molecules through ionic bonding. They form molecules through covalent bonding, in which the atoms share electrons.
Ionic bonds.
Polar molecules
Ionic bonds is the attracting between opposing forces (positive and negative) while covalent bonds are atoms sharing electrons to get an inert gas configuration (8 electrons in valence shell). Covalent bonds exist as discrete molecules while ionic compounds do not exist as discrete molecules and form large crystal lattices.
Compounds with covalent bonds form molecules. Compounds with ionic bonds form ionic lattices.

Ionic bonds
Combinations of atoms from a metal and a non-metal form ionic bonds in most cases.
