Metals and Non-Metals – Outcomes List the state and colour of two metallic elements and two non-metallic elements. Recall that metals conduct electricity and heat. Give some applications of metals. Recall the symbols for the metallic elements copper, zinc, aluminium, iron, silver, and gold. Recall the symbols for non-metallic elements carbon, oxygen, sulfur, hydrogen, and nitrogen. Describe metals as lustrous, malleable, and ductile. Give the uses of some alloys – solder, steel, and brass.

List State and Colour

List State and Colour Metals are usually solids at room temperature. Non-metals are usually gases at room temperature. e.g. copper and iron are solids. e.g. nitrogen and oxygen are gases. e.g. copper is reddish brown, iron is grey. e.g. nitrogen and oxygen are colourless.

Conduction Metals are usually good conductors of electricity and heat.

Give Applications of Metals Filament light bulbs use a tungsten filament. Electricity in households travels through copper wiring. Some cooking utensils use aluminium. Cooking stoves are often made of steel. Water is transported in copper pipes. Knives and forks are often made from stainless steel. Cars are made of many different metals.

Describe Metals They are shiny (lustrous) They can be beaten into shape (malleable) They can be stretched (ductile)

Give Uses of Alloys Alloys are mixtures of metals. They usually have specific useful properties that elemental metals do not have: Alloy Components Uses Solder Historically lead and tin. Modern variations replace lead with other metals Soldering (joining) two metals together Steel Iron and carbon Support in buildings Brass Copper and zinc Musical instruments Bronze Copper and tin Statues
