What is one way to describe elements?

They are the smallest particles of any material.

They are the building blocks of matter.

They are the most expensive materials on earth.

They break down easily.

Answer: Option (a) is the correct answer.

Explanation:

An element is defined as a substance that contains same type of atoms.

For example, a spoon made up of only copper metal will contain only atoms of copper.

An element can never be broken down into its constituent particles. This is because an element itself is the smallest particle present in a substance or material.

Thus, we can conclude that one way to describe elements is that they are the smallest particles of any material.

They are the building blocks of matter.

"They are the smallest particles of any material" is incorrect. They all consist of smaller protons, neutrons, and electrons.

"They are the most expensive materials on earth" is incorrect. Most of the common elements cost less than $100/kg.

"They break down easily" is incorrect. Many elements are so stable that you can find them in the uncombined state.
