The formula of water is H20, this means that in every molecule of water:
There are 2 atoms of hydrogen and 1 atom of oxygen
So if 1 molecule of water is electrolized then 2 atoms of H and 1 atom of O
*Although it does not happen this way the gases Hydrogen and Oxygen do not exist in atomic state but in moecular state.
So, 2 molecules of water have the formula 2.H20,
In this, there are 4 atoms of Hydrogen and 2 atoms of Oxygen.
Atlast, there will be 2 molecules of Hydrogen released at the cathode(negative electrode) and 1 molecule of Oxygen at the anode(positive electrode)

cathode is negative so H+ and anode is positive so OH -
