Class XI Physical Chemistry Short note
... found that except for the hydrogen atom, the atomic masses of no other atom could be explained by protons and electrons only. For eg. Helium atom has 2 protons in the nucleus and 2 electrons in the extra nuclear part. Therefore the mass of the Helium atom must be twice the mass of proton. But its ma ...

Chemical equilibrium
In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time. Usually, this state results when the forward reaction proceeds at the same rate as the reverse reaction. The reaction rates of the forward and backward reactions are generally not zero, but equal. Thus, there are no net changes in the concentrations of the reactant(s) and product(s). Such a state is known as dynamic equilibrium.
