Zinc-66 (symbol ⁶⁶Zn) is an isotope of zinc. Here’s how we can find the number of neutrons and electrons in this isotope:
- Protons: The atomic number of zinc (Zn) is 30, meaning all zinc atoms, including zinc-66, have 30 protons.
- Electrons: In a neutral atom, the number of electrons equals the number of protons. Therefore, zinc-66 has 30 electrons.
- Neutrons: The number of neutrons is found by subtracting the atomic number from the atomic mass number. The atomic mass number for zinc-66 is 66. So, the number of neutrons is:
66−30=36neutrons
Summary:
- Protons: 30
- Electrons: 30 (since it’s neutral)
- Neutrons: 36
