Science 6 Unit 2 Atomic Adventures

Multiple Choice

Why is it important to understand the number of protons, electrons, and neutrons in an atom when studying elements like oxygen?

• Because it helps us understand the element's chemical properties and behavior.

• Because it tells us how heavy the element is.

• Because it shows us how the element looks.

• Because it helps us know the color of the element.
