Isotopes: Variations of Elements
Understanding that isotopes are atoms of the same element with the same number of protons but different numbers of neutrons, resulting in different mass numbers. Explores how isotopic abundance determines average atomic mass.
Key Questions
- How can two atoms of the same element have different masses without becoming a different element entirely?
- How do scientists calculate the average atomic mass of an element when its atoms do not all weigh the same?
- Why might knowing the relative abundance of different isotopes matter for medical, environmental, or industrial applications?
