Question

isotopes of the same element always have the same

AMU number
Z-number

Answer 1

Isotopes of the same element have different AMU numbers, due to the difference in number of neutrons

Answer 2

They do however, maintain the same number of protons, making them the same element.

Answer 3

We represent the number of protons as the Z-Number

Answer 4

number of protons is the Z-number

Answer 5

Therefore, the Z-Number remains constant across Isotopes of the same element, whilst neutron number (and hence AMU) may change.

Answer 6

So the answer would be the Z-number?

Answer 7

Yes, it would be.

Answer 8

Thanks!

Answer 9

No problem! Glad to help.
