H is a symbol for hydrogen and O is the symbol of oxygen
hydrogen has a single free electron in its valence shell and oxygen has 2 free electrons in its valence shell.
so when oxygen and hydrogen combine to form water oxygen need two atoms of hydrogen to make an inactive compound.
below is given the chemical eqn of froming water from hydrogen and oxygen
2H + O --------------------> H2O

H20.
Well the h stands for hyrdogen and the 2 after means 2 atoms of hydroge. The o stands for oxygen and since there's nothing after there is only 1 oxygen molecule.

The water molecule is made up of two hydrogen atoms (symbol is H) and one oxygen atom (symbol is O).

You're yanking my chain, right? No? This is a serious question? OK..............
A molecule of water consists of one atom of oxygen covalently bonded to two atoms of hydrogen.

It just is. Two hydrogen atoms and one oxygen atom per molecule.
