Question

Compared with ³¹P,the radioactive isotope ³²P has
A)a different atomic number.
B)a different charge.
C)one more proton.
D)one more electron.
E)one more neutron.

Accepted Answer

Isotopes have the same atomic number (A.Z) but different neutron numbers (N), so ³²P has one more neutron than ³¹P. It does not have a different atomic number (A.Z), charge, proton, or electron.
