Atoms (Continued)

One hundred eighteen (118) elements exist. It takes at least two atoms to make one molecule, i.e. water (H2O). By using various combinations of molecular formulas from only 100 different kinds of atoms ( and 150-200 subatomic particles, see foot note #11.)more than 12,000,000 substances exist.14 By 1932 science and technology was advanced to the point where high energy could be developed safely by splitting the atom through controlled nuclear disintegration; fission. Later (1945), using that similar technique of splitting the atom to make the atomic bomb was devised and helped end World War II.15
