Which statements about isotopes are correct?
Hints
- Three follow from sharing Z; one confuses neutrons with electrons.
- A neutral atom has electrons equal to protons, and isotopes share the proton count.
Show the answer
- B. They have the same number of protons
- C. They have different numbers of neutrons
- D. They occupy the same position on the periodic table
Why
Isotopes share , so they share proton count, position on the table, and, when neutral, electron count too. Only the neutron count, and therefore the mass, differs.
