Mass numbers of isotopes is the sum of the protons and neutrons. If the same element the atoms must have the same number of protons (different protons = different elements) so the mass numbers are different only because they have different numbers of neutrons.

Ex: a;; carbon atoms must have 6 protons, most carbon atoms have 6 neutrons also, this they are carbon-12. Some carbon atoms have 8 neutrons so these are carbon-14.

What are atoms of the same element but with different masses?

Atoms of the same element that have different masses are called isotopes of the element. The presence of different numbers of neutrons in the nucleus is responsible for the existence of isotopes of an element.


Is it possible for atoms of the same chemical element to have different masses?

Yes, different isotopes of the same element have different masses.

What do you call atoms of the same element with different atomic masses?

They are called isotopes. They have different mass nmbers because they have a different number of neutrons.


Atoms of the same element with different atomic masses?

Isotopes are atoms of the same element with different atomic masses, characterized by the number of neutrons in the nucleus. Despite having different masses, isotopes share the same number of protons and electrons. Certain isotopes may be unstable, leading to radioactive decay.


Isotopes are forms of the same element that differ in what?

Yes, isotopes of an element are the same element but with different numbers of neutrons in the nucleus and thus different atomic masses.


What are atoms of the same element with different masses called?

These are known as isotopes.


Substances that are the same chemical element but have different masses are called?

How are isotopes different from state atoms?

The atoms of a chemical element can exist in different types. These are called isotopes. They have the same number of protons (and electrons), but different numbers of neutrons. Different isotopes of the same element have different masses.


Are the Isotopes are atoms of the same element with the same number of protons and?

The isotopes of an element have the same number of protons, but different numbers of neutrons.


What atoms has different masses but the same atomic number?

Isotopes of an element have different masses but the same atomic number. Isotopes have the same number of protons and electrons but different numbers of neutrons in their nuclei.


What are atoms of the same element thay have different atomic masses?

Atoms of the same element that have different atomic masses are called isotopes. Isotopes of an element have the same number of protons but different numbers of neutrons. This results in variations in atomic mass while maintaining the same chemical properties.
