Can two isotopes of different elements have the same mass number?

∙ 11y ago
Yes, as an example carbon-14 and nitrogen-14 are two isotopes of different elements with the same mass number.
Other examples include hydrogen-3 and helium-3,
argon-40, calcium-40, and potassium-40
iron-58 and nickel-58 are both stable isotopes.
Potassium-40 is an interesting radioisotope that decays to argon-40 by beta decay. This decay path is used to put dates on ancient objects.
Calcium-40 is a stable isotope.
Hydrogen-3 emits a beta particle and thence decays to helium-3.
Helium-3 is the only nontrivial stable isotope that has fewer neutrons than it has protons.
Nitrogen-14 is the most common isotope in the Universe that has and odd number of protons and an odd number of neutrons. It is more common than hydrogen-2 or lithium-6.
Beryllium-9 is the only stable isotope of an element -- that only has one stable isotope -- that has an even number of protons (4) and an odd number of neutrons (5).

∙ 13y agoNo, 2 isotopes of the same element have the same number of protons, but different number of neutrons. It is these 2 particles that determine Atomic Mass.

∙ 11y agoAbsolutely not. Having the same atomic number but two different atomic mass numbers is what MAKEs them isotopes.

Mass number of first 20 elements?
Mass number is term used for isotopes, not for elements. And it is boring to list here all the isotopes of the first 20 elements.
What makes isotopes different from elements on the periodic table?
isotopes of a given element have the same atomic number (or number of protons) but vary in the number of neutrons and hence the mass number.
Do Isotopes of uranium have different atomic numbers?
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).
Which two notations represent atoms that are isotopes of the same element?
The two notations represent atoms that are isotopes of the same element is 121 Sn and 119 Sn. The atomic mass of an element is defined as the weighted average mass of that elements naturally occurring isotopes.
What is the atom with same atomic number but different mass number?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
What isotopes of uncharded elements have different numbers?
The atomic number of the isotopes of an element is identical; the mass number is different.
Why the mass number of the same atom of an element is not constant?
Since you have isotopes of elements. Isotopes are elements with different number of neutrons hence why the different atomic masses for the same elements.

What do elements of isotopes have differently?
Because of the difference in mass number. Isotopes must have different numbers of neutrons.
Which isotopes of uncharged elements have different numbers?
The isotopes of the same element has the same atomic number. But the mass number (atomic mass) is different.
Mass number Why is it not the number on the periodic table?
Elements have different isotopes and each isotope will have different atomic mass. As such it is not possible to list the mass number of all the isotopes on the periodic table. However, the atomic mass is generally given on the periodic table which is generally calculated taking into account all the isotopes and its percentage.
What property is different in and isotope of an element?
Isotopes of elements vary by number of neutrons and thus by mass.
Mass number of first 20 elements?
Mass number is term used for isotopes, not for elements. And it is boring to list here all the isotopes of the first 20 elements.
What makes isotopes different from elements on the periodic table?
isotopes of a given element have the same atomic number (or number of protons) but vary in the number of neutrons and hence the mass number.

What does isotopes have to do with mass numbers?
isotopes of the same element have different mass number
