What is an element that has the same atomic number but different mass numbers?
Isotopes are elements that have the same number of protons (atomic number) but different numbers of neutrons, resulting in different mass numbers. For example, Carbon-12 and Carbon-14 are isotopes of carbon.
What is the difference between isobar and isotope?
isobars are elements with same mass numbers (Atomic Mass) and different atomic number (number of proton or electron)
What is the relationship between two elements X and Y whose atomic numbers are 18 and 20 respectively but their mass numbers remain same as 40?
Elements X and Y with atomic numbers 18 and 20, respectively, are argon (Ar) and calcium (Ca). Despite having the same mass number of 40, they are different elements because they have different numbers of protons in their nuclei; argon has 18 protons, while calcium has 20. The fact that their mass numbers are the same suggests they can exist as isotopes or in a specific isotopic form under certain conditions, but in this case, they are simply different elements with different properties.
How Is it possible for the atoms of different elements to have the same mass numbers?
It is possible only because of different number of neutrons.
What same mass numbers do isotopes have?
Mass numbers of isotopes are different.

Can an atom of two different elements have the same mass number?
Yes. The mass number is basic to the different elements, even more useful than the atomic number. (Unless it is an isotope. Isotopes have a different amount of neutrons than the basic element atom which makes a difference in mass number too. So, a difference in mass numbers doesn't always mean it is a different element.)

What name is given to elements with the same number of protons but differing numbers of neutron?
isotopes
Which isotopes of uncharged elements have different numbers?
Isotopes of uncharged elements have the same number of protons (which determines the element), but different numbers of neutrons. For example, carbon-12 and carbon-14 are isotopes of carbon with different numbers of neutrons but the same number of protons.
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).
When two atoms appear to have the same mass number they?
When two atoms appear to have the same mass number, it means they have the same total number of protons and neutrons. However, they may have different atomic numbers, meaning they are different elements. This can occur with isotopes, where atoms of the same element have the same mass number but different numbers of neutrons.
What same mass numbers do isotopes have?
Mass numbers of isotopes are different.
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.
How do isotopes differ and why is the atomic number of elements not a whole number?
Isotopes differ from each other by having different numbers of neutrons but the same number of protons since they are only the same element if they have the same number of protons. Atomic numbers aren't whole because their mass is based of the mass of hydrogen and amu's (atomic mass units) and due to how elements are formed, minute amounts of mass are lost in order to form the nuclear bonds resulting in not whole numbers.
