What are the properties of metals? malleable (easy to bend) shiny solid sonorous (makes a sound) good conductor of electricity Properties of metals dense strong Point out the metal exceptions which do not display these properties, e.g. mercury, sodium. high melting point good conductor of heat ductile (can be drawn into wires) high boiling point Do all metals have these properties?

Metals and non-metals – true or false?

Properties of metals and non-metals

Metals and non-metals in the periodic table The periodic table is a list of all the known elements which are arranged according to the similarities in their properties. Non-metals are mostly on the right. Metals are on the left and in the centre. Xe

Task: On your periodic table, shade the metals red the metalliods yellow and the non-metals blue.

Metal Structure A metal consists of a regular arrangement of positive ions held together by a 'sea' of electrons. The electrons can move freely, but the positive ions usually can only vibrate in the one spot. Note This type of metal bonding between positive ions and electrons in metals is strong giving metals high melting points.
