What is a isitope?

Answer 1

First of all , it is correctly spelled as 'ISOTOPE'.

A classical definition of an isotope is ' An isotope has a different number of neutrons, in its nucleus'.

Taking the atoms of any given element, their atomic masses may vary, because of the different number of neutrons present.

Carbon has three isotopes. They are

Carbon -12 ; 6 protons, and 6 neutrons/

Carbon -13 ; 6 protons and 7 neutrons (used in nuclear magnetic resonance(nmr)).

Carbon - 14 ; 6 protons and 8 neutrons (used in carbon dating).

Notice in each case the different number of neutrons, so these atoms of carbon are different isotopes.

Answer 2

Do you mean ISOTOPE? an isotope is a from of an element which has the same number of protons and electrons but a different number of neutrons. examples: chlorine (Cl) has an atomic massof 35.5 because of its isotopes. the same is apparent of bromine.

Answer 3

Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons in their nucleus. This results in isotopes having the same chemical properties but different atomic masses.

Answer 4

Isotope are atoms of the same element that have different numbers of neutrons in the nucleus. Therefore have different atomic weights.
