How Elements Bond
-
double and triple bond
When three pairs of electrons are shared by two atoms, the bond is called a triple bond.
When two pairs of electrons are involved in a covalent bond, the bond is called a double bond

Chemical Formula
a combination of chemical symbols and numbers that shows which elements are present in a compound and how many atoms of each element are present
Ammonia, is a covalent compound that contains one nitrogen atom and three hydrogen atoms. Its chemical formula is NH3.
A water molecule contains one oxygen atom and two hydrogen atoms, so its formula is H2O
