Which statements about isotopes are correct?
Hints
- Isotopes differ in neutrons only, ask what that changes and what it does not.
- Chemistry is driven by electrons, so consider whether it is affected at all.
Show the answer
- A. Same atomic number, different mass number
- C. Same number of protons, different number of neutrons
- D. Same number of electrons in neutral atoms
Why
Isotopes have the same Z and electron count, so nearly identical chemistry. They differ only in neutron count and mass.
