# Explain the difference between mass and weight.

Isotopes are variations of the same chemical element with differing numbers of neutrons and, subsequently, different atomic masses. Learn how scientists consider isotopes when they calculate average atomic mass. When you step onto a scale, you find out how much you weigh. But what does weight very measure, and what makes it vary depending on the object ? Read more to find out.
