Metals and Non-metals 01

This KS3 Science quiz takes a look at metals and non-metals. Dividing chemical elements into groups can be helpful. One of the simplest groupings is to split them up according to whether they are metals or non-metals. The periodic table is a list of all of the elements that we know about and it turns out that there are many more metals than there are non-metals. The non-metals are found on the right hand side of the periodic table, where they are divided off from the metals by a zig-zag line.

The metals and non-metals have very different chemical and physical properties (ways in which they behave). Metals conduct electricity, but non-metals don't. Metals can be bent and hammered into shapes without breaking, non-metals shatter. Metals form alkalis and non-metals form acids. There are many other properties too, usually they are opposites. There are exceptions to the rules as well, for example, the metal mercury is a liquid at room temperature but all other metals are solids.

The list which best describes the properties of metals is .......
strong, good conductor of heat and electricity, solid
strong, poor conductor of heat and electricity, shiny
weak, ductile, good conductor of heat and electricity
weak, low melting point, poor conductor of heat
Some metals conduct heat and electricity better than others
The correct way to write the symbol for the metal chromium is .......
If the symbol contains two letters, the first is a capital so that immediately rules out the second and the fourth options
The most abundant metal in the Earth's crust is .......
There is 8.2% aluminium in Earth's crust found as bauxite, aluminium oxide, never as the element
The list which contains only metals is .......
aluminium, copper, nitrogen
iron, oxygen, hydrogen
iron, silver, aluminium
iron, sulfur, copper
Nitrogen, oxygen, hydrogen and sulfur are all non-metals
Where are the non-metallic elements found in the periodic table?
In the middle
In the top rows
On the left-hand side
On the right-hand side
Some of the elements either side of the dividing line show properties of both metals and non-metals, for example silicon conducts electricity but cannot be bent or hammered into shape - it shatters
A metal which is used in jewellery is .......
It is less expensive than gold and platinum and will stay shiny for a long time
A metal, such as platinum, may be used in jewellery as .......
it is shiny and reactive
it is shiny and unreactive
it is soft and a good conductor of heat
it is soft and cheap
People like jewellery to be shiny and to stay shiny. Unreactive metals like gold and platinum take a long time to tarnish (lose their shine)
Bronze is an alloy. It is composed of .......
copper and tin
copper and zinc
iron and zinc
lead and tin
An alloy is a mixture of metals
The approximate number of elements we know about today is .......
It is quite possible scientists will discover even more elements
The filament of a light bulb consists of the metal .......
Tungsten has the highest melting point of all pure metals at 3,422°C
