If two atoms are different isotopes of the same element, the two atoms have the same..
1. number of neutrons.
2. mass number and number of neutrons.
3. atomic number.
4. number of neutrons and atomic number.
5. mass number.
Help please :) thank youu!

atomic number
The atomic number is the number of protons in the nucleus and defines the element. Different isotopes of the same element will have a different number of neutrons, therefore a different mass number.

3. atomic number.
Remember, isotopes by definition are two substances with the same number of protons (atomic number), but different number of neutrons ie different mass.

3. atomic number
remember Isotopes means ' two( or more) different atoms of same element having "same atomic number" and "different atomic masses"
so clearly the answer is "3" .
