The Periodic TableInteractive Periodic Table; www.ptable.comGI Metals – light grey, react vigorously with water – release Hydrogen gas – reaction gets more vigorous as you go down the group.

GVII HALOGENS toxic reactive gases, liquids & solids – reactivity DECREASES as you go down!

The Periodic Table

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.comhttp://www.webelements.com/

Identify any possible trends in the layout of elements.

The Periodic Table

IVIII

ColumnsGroups

= Rows

The number of VALENCE ELECTRONS for any element equals it’s GROUP NUMBER

Periods II III IV V VI VII<-- Group Numbers -->

• 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.

• The number is often written as a MINUS (for non metals) - this represents the charge formed. (Negative because electrons gained)
