Which statement is true about two isotopes of the same element? (1 point)

they have the same mass number.

they have different numbers of protons.

they have different locations on the periodic table.

they have different numbers of neutrons.

They have a different number of neutrons. What defines what kind of element something is is how many protons it has. Hydrogen will always have 1 proton, because that's what makes it hydrogen. However, it is allowed to have different numbers of neutrons, like 0,1, or 2. They are all in the family of Hydrogen, but they are different isotopes of hydrogen. Hope this helps!
