Multiple choice

Bronze is

  1. an alloy

  2. a mixture

  3. a compound

  4. an element
Reveal answer Fill a bubble to check yourself
B Correct answer
Multiple choice

A metal in chemistry is an element which

  1. loses electrons

  2. gains electrons

  3. conducts electricity

  4. is shiny
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In chemistry, metals are defined by their chemical behavior, specifically their tendency to lose valence electrons to form positive ions (cations). While metals also conduct electricity and are shiny, these are physical properties rather than the fundamental chemical definition. Non-metals tend to gain or share electrons.

Multiple choice

Carbon dioxide is

  1. an element

  2. a compound

  3. a mixture

  4. an alloy
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Carbon dioxide (CO2) is a chemical compound because it consists of carbon and oxygen atoms chemically bonded together in a fixed 1:2 ratio. It is not an element because it can be broken down into simpler substances, nor is it a mixture or an alloy.

Multiple choice

Magnesium is a

  1. Group 1 Metal

  2. Group 2 Metal

  3. Group 3 Metal

  4. Group 4 Metal
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Magnesium is located in the second column of the periodic table, making it a Group 2 alkaline earth metal. Group 1 contains alkali metals like sodium, while groups 3 and 4 contain transition metals.

  1. Iron is used to make planes

  2. Aluminium is used to make jewellery

  3. Gold is used to make buildings

  4. Copper is used to make electrical wires
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Copper is an excellent conductor of electricity and is widely used in electrical wiring. Iron is generally too heavy/corrosive for planes, gold is too soft for buildings, and aluminium is used for planes, not jewelry.

Multiple choice
