Question

scientists are working with a liquid that is made of only one type of atom. which statement correctly describes this liquid?
the liquid contains only one compound.
the liquid contains only one element.
the liquid contains only neutral electrons.
the liquid can be broken down into simpler substances.

Explanation:

An element is defined as a pure substance composed of only one type of atom. A compound is made of multiple different atoms bonded together, so the first option is incorrect. Electrons are subatomic particles, not the building block of the liquid itself, so the third option is wrong. Elements cannot be broken down into simpler substances by chemical means, so the fourth option is also incorrect.

Answer:

The liquid contains only one element.
