Approved Tutor Answer11 Months agoZirconium has an atomic number of 40, which means it has 40 protons in its nucleus. To find the number of neutrons in an isotope, you can use the formula:
Calculating Neutrons
The number of neutrons can be calculated by subtracting the atomic number from the mass number of the isotope. For zirconium₉₂, the mass number is 92.
Formula
- Neutrons = Mass Number - Atomic Number
Applying the Values
Using the values for zirconium₉₂:
- Mass Number = 92
- Atomic Number = 40
Now, plug in the numbers:
Neutrons = 92 - 40 = 52
Final Answer
Therefore, the isotope zirconium₉₂ contains 52 neutrons.
