Answer 3

Isotopes differ from each other because they ____.
Select one:
a. have different properties
b. have different electron configuration
c. have a different number of protons
d. have more or fewer neutrons

Answer 4

Isotopes are the different forms of an atom of a specific element.
They are all the same element, but have different weights, because they have the same number of protons, but a different number of neutrons.

Answer 5

For example, Carbon-12 is an isotope of carbon that has 6 protons and 6 neutrons.
Carbon-14 still has 6 protons (it's the same element), but it has 8 neutrons.
Both are isotopes of the element carbon.
