The isotopes of an element must have a different amount of neutrons.
I'm pretty sure you know what these are, but just in case:
A neutron is a sub-atomic part of an atom, together with protons and electrons.
An atom or element that have different masses are known as isotopes.
Isotopes have a different number of neutrons.
The isotopes have different masses.
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.
elements are isotopes, when different atoms of the same element have different number of neutrons
An atom or element that have different masses are known as isotopes.
what are the names of 15 different isotopes
Isotopes have a different number of neutrons.
The isotopes have different masses.
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.
elements are isotopes, when different atoms of the same element have different number of neutrons
Isotopes of the same element have different numbers of neutrons and mass.
If they have the same atomic number but different mass, then they have a different number of neutrons, and they are called ISOTOPES.
Isotopes. They differ in the number of neutrons in the nucleus.
If an atom of the same element has the same number of protons but a different number of neutrons, then they are isotopes.
Isotopes have a different number of neutrons.
Isotopes have different number of neutrons.
