No. By definition isotopes of an element have the same number of protons (that is what makes them uranium, for example) but different numbers of neutrons (neutral particules in the nucleus which provide mass).

∙ 15y agoNo. If they had different atomic numbers, they would not be the same atom and would be different elements. Different isotopes have different mass numbers.

What do you called in an element having the same atomic number but different atomic masses?
Isotopes. eg U235 and U238. Both Uranium, atomic number 92, bur different isotopes.
Atoms that have the same atomic numbers but different atomic weights are called what?
If they have the same atomic number but different mass, then they have a different number of neutrons, and they are called ISOTOPES.
What are the similarities and differences between the isotopes uranium 235 and uranium 238?
Uranium-235 has 143 neutrons and uranium-238 has 146 neutrons. And of course the atomic masses are different.
Which is the average of the mass numbers of an element's isotopes?
the Atomic Mass
The various atomic weights of the same element are called?
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).
What do you called in an element having the same atomic number but different atomic masses?
Isotopes. eg U235 and U238. Both Uranium, atomic number 92, bur different isotopes.
Isotopes of hydrogen have different atomic what?
Atomic mass and different numbers of neutrons.
Does an isotope of an element have a different atomic mass?
Yes; isotopes of the same element have the same atomic number but differ in their atomic masses.
Do the atomic numbers of such isotopes differ?
No. Isotopes have the same atomic number, protons and electrons. They have different neutrons.
What does it mean if two atoms are isotopes?
If two atoms are isotopes, it means they have the same number of protons but different numbers of neutrons. Thus, they have the same atomic numbers, but different atomic masses.
Atoms that have the same atomic numbers but different atomic weights are called what?
If they have the same atomic number but different mass, then they have a different number of neutrons, and they are called ISOTOPES.
Do uranium isotopes have different atomic masses?
Yes, each isotope has a specific atomic mass; this is correct for all the elements.
Do isotopes of an element have the same atomic mass but different atomic number?
The different mass numbers are due to different numbers of neutrons.
What are the similarities and differences between the isotopes uranium 235 and uranium 238?
Uranium-235 has 143 neutrons and uranium-238 has 146 neutrons. And of course the atomic masses are different.
How are isotopes of the same element named?
The same name with a different atomic mass number. As an example U235 and U238 are two isotopes of Uranium
Form of an element having different atomic and number of neutrons?
Isotopes have different numbers of electrons, but not different atomic numbers (numbers of protons) or they'd be different elements.
What isotopes of uncharded elements have different numbers?
The atomic number of the isotopes of an element is identical; the mass number is different.
