Everything is made up of tiny particles called atoms. The atom is indivisible. Atoms cannot be created or destroyed. Elements are made up of only one type of atom. Atoms join together in chemical reactions. Atoms contain tiny negatively charged particles called electrons. The rest of the atom is positive to balance out the charge, and the electrons are embedded in this like pieces of fruit in a pudding. The positive charge and mass of the atom is concentrated in a tiny nucleus in the centre of the atom. The electrons exist randomly in the space around the nucleus.
