I think you are referring to Isotopes. They have the same atomic number but different atomic masses. This is due to differences in the numbers of neutrons.

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.


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.


What are atoms of an element that have the same atomic number but different weights referred to as?

Isotopes The weights are different because the quantity of neutrons are different. However, the Isotopes still have exactly the same number of protons and electrons as each other, so they are chemically identical. Just the weights are different.


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.


Two atoms with the same atomic number but different atomic weight?

Two atoms with the same atomic number but different atomic weight are known as isotopes. Isotopes have the same number of protons and electrons, but a different number of neutrons, resulting in different atomic weights. For example, carbon-12 and carbon-14 are isotopes of carbon with the same atomic number (6) but different atomic weights due to a difference in neutron count.


Do radioactive atoms have different atomic weights than non radioactive atoms of the same element?

yes


Do all elements have the same atomic weight?

No they are all different and even some atoms of the same element have different weights


What isotopes are atoms of the same elements with different number of?

Isotopes are atoms of the same elements with different number of neutrons.


Are atoms of the same element that have the same number of protons but have different number of neutrons?

Isotopes are atoms of the same element, having the same number of protons but different number of neutrons.


Do all atoms of the same element contain the same number of netrons?

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.


What is the name given to atoms of the same element that have the same number of protons?

Atoms of the same element cannot have different numbers of protons. Different numbers of protons mean different elements. An atom with the a different number of neutrons is called an isotope.


Atoms of the same atomic are called what?

isotopes Atoms of the same element are called Isotopes. they have the same number of atoms (i.e. same atomic number) but different number of neutrons
