How many neutrons are there is the nuclei Zn66?
Correct answer: B. 36
- A. 22
- B. 36
- C. 30
- D. 66
Explanation
The following is the solution: The number 66 in "Zn66" represents the mass number of the nuclide, which is the total number of protons and neutrons in the nucleus of an atom. The atomic number of an element represents the number of protons in its nucleus. For zinc (Zn), the atomic number is 30. To find the number of neutrons, you can subtract the atomic number from the mass number: Neutrons = Mass number - Atomic number. For Zn66: Neutrons = 66 - 30 = 36.
