Quiz Answer Key and Fun Facts

1. Which of the following subatomic particles are not in the nucleus of an atom?

Answer: electron

An atom is somewhat similar to a solar system. In the middle is the nucleus, in which there are neutrons and protons. Revolving around them are electrons. Unlike protons and neutrons, electrons have negligible mass.

2. Which of the following subatomic particles have positive charge?

Answer: protons

Protons are positively-charged while electrons are negatively-charged. Neutrons possess no charge. So the charges are balanced, an atom consists of an equal number of electrons and protons. If an atom loses electrons, it becomes positively charged and if it gains electrons, the atom becomes negatively charged.

3. Which of the following statements about sodium is not true?

Answer: If its oxide is added to water, an acid is formed

Sodium (Na), with atomic number 11, is a reactive metal and has to be kept in kerosene in the laboratory. However, it is a soft metal like potassium (K). It forms sodium hydroxide (NaOH), a base, when its oxide is added to water. Non-metals form acids when their oxides are added to water.

4. Which of the following elements is NOT a noble gas?

Answer: Francium

Francium is actually a very reactive metal. The noble gases include helium, neon, argon, krypton, xenon and radon. They are non-reactive as they have their shells filled. Hence, they are known as 'noble' gases.

5. Which of the following non-metals is a liquid at room temperature?

Answer: Bromine

Bromine is the only non-metal which is a liquid. Oxygen is a gas while phosphorus is a solid. Platinum is a solid metal.

6. This noble metal is the most malleable and ductile metal as well. You need aqua regia to dissolve it. It is very lustrous and yellow in colour. What is the name of this element?

Answer: Gold (Au)

Aqua regia is a mixture of nitric acid and hydrochloric acid in a ratio of 1:3. The symbol of gold (Au) is comes from its latin name 'aurum'. Osmium is the densest metal. Silver is the best electrical and thermal conductor. Platinum is the most non-reactive metal.

Answer: Nitrogen

Nitrogen makes up 78% of the air and is essential for plant growth. It has a valency of 3 and is a non-metallic gas. It occurs naturally as a diatomic molecule.

8. Which of the following are the products when an acid reacts with a base in a neutralization reaction?

Answer: A neutral salt and water

Example of a neutralization reaction:
3H2SO4 + 2Al(OH)3 gives Al2(SO4)3 + 6H2O
Here, an acid (sulphuric acid) and a base (aluminium hydroxide) neutralize each other to produce a neutral salt (aluminium sulphate) and water.

9. I am adding some copper sulphate solution to sodium hydroxide. Which of the following results would you expect?

Answer: A precipitate will form.

The reaction results in the formation of copper hydroxide (which will precipitate from solution) and sodium sulphate.
Sodium hydroxide is used in the manufacture of detergents.
Copper sulphate is used in the dying industry, as a wood preservative and as a fungicide in the form of Bordeaux mixture.

10. Which metal would you obtain from bauxite ores? Its oxides are what compose the mineral corundum. You might find it used as foils due to its malleability.

Answer: aluminium

With an atomic number of 13, aluminium is known for its malleability and thus is used in foils. Being quite light, aluminium is used in construction work, automobiles and transportation. Aluminium is used in mirrors as it is very reflective.
