All carbon atoms have six (6)protons but the number of neutrons can be six (6), seven (7), or eight (8). Different neutron numbers ____.
A)force the atom to bond with elements that it normally would not
B)change the atom's atomic mass number and make it an isotope
C)cause the atom to be more or less reactive
D)change the atom's atomic mass number and make it an ion
E)cause the atom to be unstable

Question

Quizplus · Accepted Answer

Different neutron numbers change the atom's atomic mass number, creating isotopes. Isotopes of the same element have different atomic masses but the same number of protons, leading to differences in physical and chemical properties.
