This question is about elements, compounds and mixtures.

Substance A contains only one type of atom.

Substance A does not conduct electricity.

Which type of substance is A?

• compound

• metallic element

• mixture

• non- metallic element

Substance B contains two types of atoms.

The atoms are chemically combined together in fixed proportions.

Which type of substance is B?

• compound

• metallic element

• mixture

• non- metallic element

What is the name of the elements in Group 0 of the periodic table?

• Alkali metals

• Halogens

• Noble gases

• Transition metals

Which statement about the elements in Group 0 is correct?

• All elements in the group are very reactive.

• The boiling points increase down the group.

• All elements in the group form negative ions.

• The relative atomic masses (Ar) decrease down the group.

Neon is in Group 0.

What type of particles are in a sample of neon?

• atoms

• ions

• molecules

Fine and coarse particles of the metallic element are also cubes.

The length of a fine particle cube is 10 times smaller than the length of a

coarse particle cube.

How does the surface area to volume ratio of the fine particle cube compare with that of the coarse particle cube?

• Both surface area to volume ratios are the same.

• The surface area to volume ratio of the fine particle is 10 times greater.

• The surface area to volume ratio of the fine particle is 10 times smaller.

This question is about chemical cells and batteries.

Three different types of battery can be used to power a TV remote control.

Give one advantage of each type of battery.
