Elements are made from atoms—the smallest particle of an element that can take part in chemical reactions. Atoms have three main components protons, neutrons and electrons. Protons are positively charged, with a mass similar to that of the hydrogen atom. Neutrons are uncharged and of equal mass to protons. Electrons are about 1/1836 the mass of protons, with a negative charge of equal value to the (positive) charge of protons. [Pg.3]
