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.
An atom or element that have different masses are known as isotopes.
Isotopes are atoms of the same elements with different number of neutrons.
Isotopes are atoms of an element having different number of neutrons.Ions are atoms with an electrical charge.
Isotopes are atoms of the same element but with a different number of neutrons.
All atoms of an element contain the same number of electrons and protons but they can have different numbers of neutrons. Atoms with different numbers of neutrons are isotopes.
An atom or element that have different masses are known as isotopes.
Isotopes are atoms of the same elements with different number of neutrons.
Isotopes can be found in any element. A definitive statement on an isotope is ' An Atom has a different number of neutrons'. The element that exhibits in large proportion two isotopes is chlorine. There is Chlorine-35 & Chlorine-37 The numbers being the atomic masses of of chlorine. The difference of '2' ( 37-35) is made up by a different number of neutrons. Chlorine-35 ; 17 protons, 18 neutrons and 17 electrons Chlorine-37 ; 17 protons. 20 neutrons and 17 electrons. The atomic Mass of Chlorine is given as 35.5 . This because there are 75% of Cl-35 atoms and 25% of Cl-37 atoms. NB Not all isotopes are Radio-Active, but some are!!!!!
Isotopes are atoms of the same element with different numbers of neutrons. Mixtures, on the other hand, are combinations of different substances that are physically mixed together, but not chemically bonded.
Isotopes are atoms of an element having different number of neutrons.Ions are atoms with an electrical charge.
Atoms that vary in the number of neutrons found in their nuclei are called isotopes. Isotopes of an element have the same number of protons but different numbers of neutrons, which can lead to variations in their atomic mass.

All atoms of an element contain the same number of electrons and protons but they can have different numbers of neutrons. Atoms with different numbers of neutrons are isotopes.
Isotopes are atoms of the same element that have different numbers of neutrons in their nuclei. This leads to variations in atomic mass for isotopes of the same element.
Isotopes are atoms of the same element that are only different by the number of neutrons they have
They are called isotopes,
If two atoms are isotopes, it means they have the same number of protons but different numbers of neutrons. Thus, they have the same atomic numbers, but different atomic masses.
