Science Revision Notes Chemistry Atoms are the smallest particle of a particular element. Molecules are particles that contain 2 or more atoms joined together by chemical bonds. Elements are substances that are made up of only one type of atom. Compounds are substances form when two or more elements are joined chemically. Metals are solid at room temperature‚ with the exception of mercury. Metals are good conductors of electricity and heat. Metals can usually be melted at high temperatures. Non-metals

1) Demonstrate understanding of the terms atom and molecule. Atom= Smallest Unit of Matter Molecule= 2 or more atoms chemically bonded. 2) Describe paper chromatography. 3) Interpret simple chromatograms. A method used to separate a Solution‚ using a Paper and a beaker of water. The Substances in the Paper go up depending on their Mass. We can say that a Solution has the same substance as another solution because they form a line of the same height. 4) Describe methods of separation

Chemistry Revision F331 Isotopes - atoms with the same atomic number‚ but different mass numbers 131I - radioactive tracer for thyroid. 99Tc for tumours. Radioisotopes - gamma emitters & short half life - long enough to detect‚ but not long enough for damage. Beta particles emitters are more useful than alpha particle emitters because they penetrate more and so are more easily detected. Also‚ less damaging. The half life is the time taken for half the isotope to decay Mass left = initial
