Periodic table, in chemistry, the organized array of all the chemical elements in order of increasing atomic number. When the elements are thus arranged, there is a recurring pattern called the ‘periodic law’ in their properties, in which elements in t

As we have seen, the number of electrons spinning around a nucleus is usually the same as the atomic number, so that their charges cancel out resulting in a neutral atom (neutrons are also electrically neutral, hence the name, so they don't contribute anything to the overall charge of the...
