Atoms for Peace is a term coined by US President Dwight D. Eisenhower in 1953 to describe the peaceful use of nuclear energy. The term refers to the use of atomic energy for peaceful purposes, such as power generation and medical research. MOL stands for 'MOLECULE, ' which is the smallest unit of matter that can exist independently. An atom is made up of protons, neutrons, and electrons, and molecules are made up of atoms. Isotopes are atoms of the same element that have different numbers of neutrons, which makes them have different atomic masses. Isotopes are important in many scientific fields, such as medicine, geology, and chemistry.
