Elements – different types of atom

Elements – different types of atom

Elements – different types of atom. Elements are the simplest substances. There are about 100 different elements. Each element is made up of very tiny particles called atoms , and each element is made up of just one particular type of atom, which is different to the atoms in any other element.
