Metals Quiz

1. In an iron atom that has not reacted with anything, the number of electrons is always equal to the number of:

Protons

Neutrons

Particles in the nucleus

2. An isotope of uranium which has not reacted with anything would have the same number of protons but a different:

Number of electrons

Atomic number

Number of neutrons

3. Another word for corrosion is:

Neutralisation

Rusting

Exploding

4. Neutralisation occurs when an acid reacts with a base. When this occurs, the products of the reaction are always:

An acid and a carbonate

A sugar and water

A salt and water

5. When iron is exposed to moist air, corrosion occurs. The word equation for this reaction is Iron + oxygen + water -->

Iron hydroxide

Iron and a salt

Salty water

6. When magnesium is put into hydrochloric acid, the reaction that occurs gives off a gas and leaves a salt behind. The word equation is magnesium + hydrochloric acid -->

Magnesium chloride + oxygen gas

Magnesium chloride + hydrogen gas

Magnesium chloride + nitrogen gas

7. The current theory related to atomic structure states that the nucleus is at the centre and contains the:

Protons and neutrons

Electrons and neutrons

Protons and electrons

8. Arranged in shells around the nucleus and orbiting the nucleus in these shells are the:

Protons

Neutrons

Electrons

9. In the periodic table of elements, the elements are arranged in order of their:

Number of protons

Weight

Names

10. In the periodic table of elements, metals appear:

On the left side

On the right side

All over

11. How many protons does the metal Zinc have?

65

30

18

12. When calcium carbonate reacts with hydrochloric acid, a gas is released which turns limewater milky. The three products of the reaction are:

Calcium chloride + water + oxygen

Calcium chloride + water + salt

Calcium chloride + water + carbon dioxide
