Atoms of the same atomic number (= number of protons in each nucleus) can have different mass numbers because of containing different numbers of neutrons in each atom.

What are atoms with the same atomic number but different mass called?

Atoms with the same atomic number are all atoms of the same element. However, if the atoms have different molecular weights, they are isotopes of the same element.


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 describes atoms with the same number of protons and different number of neutrons?

Isotopes describe atoms with the same number of protons and different number of neutrons. These isotopes have the same atomic number but different mass numbers, resulting in variations in atomic mass.


What are atoms that have the same number of protons but different mass number?

Atoms with the same number of protons but different mass numbers are called isotopes. Isotopes have the same atomic number but different atomic weights due to variations in the number of neutrons in the nucleus.


Do isotopes have the same atomic number and different mass numbers?

Yes. Isotopes have the same atomic number because all of their atoms have the same number of protons. They have different mass numbers because their atoms have different numbers of neutrons, and mass number is the sum of the numbers of protons and neutrons.


Isotopes are atoms that have the same number of protons but a different?

Isotopes are atoms of a given element that have the same number of protons but a different mass number and therefore a different number of neutrons.


What are atoms that have different masses but the number of protons?

Atoms that have different masses but the same number of protons are called isotopes. Isotopes of an element have the same number of protons, which determines the element's identity, but a different number of neutrons, leading to variations in atomic mass.


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 are the atoms called then they have the same atomic number but different mass numbers?

They are called as isotopes in which mass number differ by emmision of radiation


How can different atoms of the same element have the same atomic number but can have different mass numbers?

They have different numbers of neutrons.


Atoms of the same element that have a different number of neutrons and a different atomic mass are what?

isotopes


What is it called when they have same atomic number but different mass?

They are called isotopes of the same element
