Elements, Mixtures & CompoundsELEMENTS atomic bod 18 the simplest substances in nature.All of the subdivisions atomic number 18 shown in a scrunch up called the PERIODIC TABLE. In this accede they ar group so that segments which be withstand in similar ship canal are in the same group.Every component part in the periodic remit is given a sign (e.g. Fe is iron, Cu is copper, O is atomic number 8)The smallest part of an atom is called an ATOMAn element contains only ONE video display case of atom - e.g. the element coppper contains only copper atoms, the element oxygen conttains only oxygen atoms and so on.A COMPOUND contains devil or more elements chemically bonded together.A MIXTURE contains different elements or compounds miscellaneous together (not bonded together)  | | This second of apparatus is called a LIEBIG CONDENSER.
