Metallic elements Exit-Quiz

Which of the following properties are most likely associated with metals? Tick 2 correct answers.

• Being a good thermal conductor

• Being brittle

• Being a poor electrical conductor

• Being malleable

Answer explanation

Metals are known for being good thermal conductors, allowing heat to pass through them easily. They are also malleable, meaning they can be shaped without breaking. In contrast, being brittle and poor electrical conductors are not typical properties of metals.

Graphite is a non-metal. Why is it unique? Tick 1 correct answer.

• It is a good thermal and electrical conductor.

• It is sonorous.

• It is found on the left side of the periodic table.

• It is shiny and ductile.

Answer explanation

Graphite is unique because it is a good thermal and electrical conductor, unlike most non-metals. This property is due to its structure, allowing electrons to move freely, making it useful in various applications.

What does 'malleable' mean? Tick 1 correct answer.

• It can be easily shaped or bent.

• It breaks easily.

• It can conduct electricity.

• It can be pulled into a wire.

Answer explanation

The term 'malleable' refers to a material's ability to be easily shaped or bent without breaking. This characteristic is commonly associated with metals, making the first answer choice the correct one.

Look at the table below and select which element is most likely to be a metal. Tick 1 correct answer.

• Element A

• Element B

• Element C

Answer explanation

Element A is most likely a metal because it exhibits properties typical of metals, such as high conductivity and malleability, which are not usually found in non-metals like Elements B and C.

True or false? The elements highlighted in green in this image are all metals. Tick 2 correct answers.

• True

• False

• hydrogen is a non-metal

• they are all non-metals

Answer explanation

The statement is false because hydrogen is a non-metal, while the other highlighted elements are metals. Therefore, not all highlighted elements are metals.
