Answer:
Isotopes
General Formulas and Concepts:
Chemistry - Atomic Structure
- Isotopes - Elements that have different amount of neutrons
Explanation:
Both given elements are the same; they will have the same amount of protons in the nucleus. The number shows us the difference in the amount of neutrons in the nucleus. Gold - 186 has 2 more neutrons than Gold - 184.
Both are the same element, but they are isotopes, or different variations, of gold.
