The number of protons, and therefore their atomic number.
Also -of coarse- the number of electrons of these two atoms are the same.
Isotopes are atoms of the same element that have different numbers of neutrons in their nuclei. This leads to variations in atomic mass for isotopes of the same element.
This question is misguided. Atoms do not have isotopes. In a sample of an element there are many atoms. They will all have the same number of protons in their nuclei, that's what makes them the same element. Individual atoms may have different numbers of neutrons, if this happens they are called isotopes. For instance in silver, all the atoms have 47 protons, but some of them have 60 neutrons and some have 62. We say that silver has two stable isotopes. Perhaps your question should be 'Do all atoms of the same element have the same number of neutrons?'
Atoms of the same element that have different masses are called isotopes of the element. The presence of different numbers of neutrons in the nucleus is responsible for the existence of isotopes of an element.
Atoms of the same element with different atomic masses are known as isotopes. Isotopes differ only by the number of neutrons present in the nucleus of the isotopes. The number of protons is the same for all isotopes of an element (because if there were different numbers of protons, then the atoms would not be of the same element).
The isotopes of an element have the same number of protons, but different numbers of neutrons.

Isotopes are atoms of the same element that are only different by the number of neutrons they have
No, atoms of the same element have the same number of protons. Atoms of the same element with different numbers of neutrons are called isotopes.
Atoms of the same element that have different masses are called isotopes of the element. The presence of different numbers of neutrons in the nucleus is responsible for the existence of isotopes of an element.

Elements with isotopic atoms? An isotope is the same form of an element, but with a different number of neutrons. An element with isotopes/"isotopic atoms" is simply an element with isotopes.
Isotopes are atoms of the same element but with a different number of neutrons.
Isotopes are atoms of the same element with different numbers of neutrons. Mixtures, on the other hand, are combinations of different substances that are physically mixed together, but not chemically bonded.
