Answer:
The number of protons is 30. Substitute the known values, where N represents the number of neutrons. Let's rewrite the equation as 30+N=65 30 + N = 65 .
Answer:
35 neutrons
Step by step explanation:
Atomic mass of Zinc: 65 amu (atomic mass units)
Number of protons in Zinc: 30
Number of neutrons in Zinc: Atomic mass of Zinc - Number of protons in Zinc = 65-30 = 35 neutrons.
Therefore, zinc atoms have 35 neutrons.
