Question

Alyssa investigates properties of matter. The answer to which question would best
determine whether a substance is an element or a compound?

Answer 1

Answer:

This question is incomplete as it lacks options, the options are:

A) What is the radius of each particle of the substance?

B) Does the substance contain more than one type of atom?

C) Was a chemical reaction necessary to create the substance?

D) What is the electrical charge of the particles of the substance?

The answer is B

Explanation:

In chemistry, an element is a substance made up of a single type of atom i.e. only one atom of the same type constitutes an element while a compound is a substance that contains two or more different elements. If a compound contains different elements, it means that a compound will certainly contain more than one type of atom.

According to this question, the best question to ask when Alyssa wants to differentiate between an element and a compound is: DOES THE SUBSTANCE CONTAIN MORE THAN ONE TYPE OF ATOM?

- If the answer is yes, the substance is a COMPOUND

- If the answer is no, the substance is an ELEMENT.

Answer 2

The question that would most adequately determine if a substance is an element or compound would be:

- Does the substance contain more than one type of atom?

Properties of matter

• An element is defined as a chemical substance that comprises of atoms having similar proton numbers.
• While a compound is made of joining a minimum of two or more elements.
• Thus, the substance having one type of atom would be called an element while having different types of elements would be called a compound.
