Answer:

Are the exact same element.

Explanation:

If two elements have the same atomic number, they are the same element.

At this point the only difference between the two would come from a difference in the number of neutrons in the atoms.

Because the two atoms have the same atomic mass, you know that they are probably the same mixture of isotopes of the element.
