Properties Of metals

Question 1

Name some metals found in the periodic table

Answer 1

Iron (Fe)
Aluminium (Al)
Copper (Cu)
Magnesium (Mg)

Question 2

What does it mean when it says METALS CONDUCT ELECTRICITY

Answer 2

This means metals allow electrical current to pass through them easily.

So metals are used to make wires to move electricity around a circuit

Question 3

Name some of the properties of metals (1 of 4)

Answer 3

Metals are:

Strong and tough - this means they do not break, so they are good building materials, eg, an iron bridge

Shiny when polished - they have a smooth surface, which means they reflect light well.

Malleable - easily shapes, this means metals can be hammered into think sheets or shaped Rich is useful for eg. cars and planes

Question 4

Name some of the properties of metals (2 of 4)

Answer 4

Metals are:

Ductile - this means they are not brittle and can be drawn into wires

Metals just bend and stretch

Eg. Copper is often used to make electrical wires because it’s bendy.

Sonorous- this means they make a nice ‘donnngggg’ sound when they get hit. It’s only metals that do this.

Question 5

Name some of the properties of metals (3 of 4)

Answer 5

Metals:

Conducts heat - this means metals let heat energy pass through them easily. Eg. Saucepans are made out of metals like aluminium so that the heat passes easily through the pan and cooks your spaghetti.

Have high melting and boiling points - a lot of heat energy is needed to melt metals and this is because their atoms are joined up with strong bonds, eg ovens.

Question 6

Name some of the properties of metals (4 of 4)

Answer 6

Metals:

Have high densities (meaning how much stuff can be squeezed into a certain space) eg. Lead is a dense metal, there are a lot of atoms in a small space.

Some metals are magnetic - meaning some metals are attracted to magnets, eg. Iron, nickel, cobalt
