Covalent bonds form between two non-metals.
Covalent bonds will never form between a metal and non-metal.
The non metals form a molecule by sharing the electrons between them to give an overall neutral charge.
There are a large number of molecules held together with covalent bonds, for example:
O2 (oxygen gas)
C2H5OH (ethanol, ie alcohol)
CO2 (carbon dioxide)
basically, any molecules that dont contain metals.
For example methane; compounds with shared electrons between atoms.
HCl is held together by a covalent bond

Cl2
A molecule is the smallest neutral unit of two or more atoms held together by a covalent bond.
The water molecule itself is held together by polar covalent bonds between the oxygen atom and the two hydrogen atoms.
The two hydrogen atoms in a hydrogen molecule are held together by a covalent bond.

I think so. Here covalent and there ionic.
Cl2
A molecule is the smallest neutral unit of two or more atoms held together by a covalent bond.
The bond in water is covalent.
Carbon monoxide is held together by a covalent bond.
The water molecule itself is held together by polar covalent bonds between the oxygen atom and the two hydrogen atoms.
polar covalent bonds
The two hydrogen atoms in a hydrogen molecule are held together by a covalent bond.
The atoms in a water molecule are held together by covalent bonds; this means that the bonded atoms have formed a hydrogen bond between them, leading to a water dimer.
