Isotopes

Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons. This means that isotopes have the same atomic number but different mass numbers. The different number of neutrons in isotopes results in variations in atomic mass.

Key Points:

• Isotopes are atoms of the same element with different numbers of neutrons.
• Isotopes have the same number of protons but different mass numbers.
• The variations in atomic mass among isotopes are due to differences in the number of neutrons.

Study Guide:

1. Define isotopes and explain how they differ from each other.
2. Describe the relationship between the number of protons, neutrons, and mass numbers in isotopes.
3. Provide examples of isotopes of common elements and their applications in various fields.
4. Explain the concept of average atomic mass and how it is calculated based on the abundance of isotopes.
5. Discuss the significance of isotopes in fields such as medicine, archaeology, and environmental science.
