6. Periodic Table Investigation On the supplied blank outline of the periodic table. Type in symbols for all the elements you know of which are: –Metals –Gasses –Liquids –Non Metals (substances that are not metals) Use some form of colour scheme to distinguish the various kinds of elements. Interactive Periodic Tables you may wish to use: www.ptable.com http://www.webelements.com/ Identify any possible trends in the layout of elements.

7. The Periodic Table I VIII Columns Groups = Rows The number of VALENCE ELECTRONS for any element equals it’s GROUP NUMBER Periods II III IV V VI VII The number of bonds made by an element is called its VALENCY. METALS: Valency = number of VALENCE electrons. = GROUP NUMBER. Non-metals: Valency = 8 - the group number.Non-metals: Valency = 8 - the group number. The number is often written as a MINUS (for non metals) - this represents the charge formed. (Negative because electrons gained)The number is often written as a MINUS (for non metals) - this represents the charge formed. (Negative because electrons gained)
