 * 13
 * recall that electrons orbit the nucleus in shells
 * recall there is a maximum of 2 electrons in the first shell, 8 in the second and 8 in the third
 * understand that atoms are more reactive the closer they are to having a full outer shell
 * fill electron shell diagrams correctly for the elements of the Periodic Table (up to Group 2 in Period 3) if given the atomic number || [[file:electron arrangement table.pdf]]

 * stable compounds have atoms with complete outer shells
 * explain why two atoms of hydrogen will react with one atom of water to form a stable compound
 * use the number of electrons in the outer shell to identify the formula of a compound such as potassium bromide
 * explain what is meant by the term ion
 * draw electron shell diagrams for ions
 * recall that metals form ions by losing electrons; non-metals form ions by gaining electrons
 * explain why metal ions will attract non-metal ions || Ilmiö 3 Ioniyhdiste p 121 || Revision for test ||  ||

 * recall ionic compounds are soluble in water, have solutions which conduct electricity, and have high melting points.
 * explain these properties using the idea of forces in ionic bonds, and the movement of electrons
 * draw covalent bonds for compounds made from a metal and non-metal
 * recall that elements bond to themselves covalently eg in H 2
