Question

Which force is responsible for the existence of isotopes?
(1 point)
gravitational force
strong nuclear force
electromagnetic force
weak nuclear force

Answer 1

The force responsible for the existence of isotopes is the **strong nuclear force**. This force binds protons and neutrons together in the nucleus of an atom, allowing for variations in the number of neutrons (while the number of protons defines the element) to create different isotopes of that element.
