Question

How many neutrons could an atom of the element zinc (Zn) have?

Im confused because its multiple choice and the only options are 30, 36, 65, and 95.... I dont know which one it is. Can someone help?

Answer 1

none of these

Step-by-step explanation:

because no.of proton+no.of neutron=atomic mass

therefore in zinc no.of protons(30)+ no.of neutrons(35) =atomic mass(65)

therefore the no.of neutrons in zinc is 35
