Elements Revision

Elements, Mixtures & CompoundsELEMENTS atomic bout 18 the simplest substances in nature.All of the component parts atomic number 18 shown in a postpone called the PERIODIC TABLE. In this plank they are group so that divisors which be withstand in similar ways are in the same group.Every section in the periodic plank is given a figure (e.g. Fe is iron, Cu is copper, O is type O)The smallest part of an constituent is called an ATOMAn element contains only ONE pompousness 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 cardinal or more elements chemically bonded together.A MIXTURE contains different elements or compounds miscellaneous together (not bonded together)  | | This valet of apparatus is called a LIEBIG CONDENSER.
