An isotope atom of an element is one with the same number of protons in the nucleus (i.e the atomic number) but with a different number of neutrons giving it a different mass.
Isotopes have the same chemistry because they have identical valence shells.
An example is chlorine which is found in nature with two stable isotopes 35Cl with 18 neutrons and 37Cl with twenty. As 35 is around 75% and 37 25% in nature the atomic weight is 35.453.

∙ 12y agoAn isotope is a type of atom that has a different number of neutrons than usual. Most Hydrogen atoms have no neutrons, but some have 1. This is an example of an isotope of hydrogen (deuterium, in this case.)

Is isotope often termed as an atom's outer shell?
No, never. An isotope has to do with the nucleus of the atom.
What is an atom called when the number of neutron changes?
an isotope of an element
What part of an atom determines the isotope of an atom?
Neutron
What is isotope effect?
isotope effect occurs when there is a difference in the rate of reaction when an atom is replaced by an isotope.
This atom is a of helium -4?
isotope
Is xenon an isotope ion or neutral atom?
It is an isotope of a neutral atom.
Can an isotope be a neutral atom?
Yes, they usually are; being an isotope does not change the chemistry of the atom.
Is isotope often termed as an atom's outer shell?
No, never. An isotope has to do with the nucleus of the atom.
Is a aluminum an isotope ion or neutral atom?
An alumimium atom is electrically neutral and it is an isotope of aluminum.
What is an atom called when the number of neutron changes?
an isotope of an element
An isotope shares the atomic number with its element atom How does it differ from the element atom?
An isotope shares the atomic number with its element atom. How does it differ from the element atom?
What part of an atom determines the isotope of an atom?
Neutron
What is isotope effect?
isotope effect occurs when there is a difference in the rate of reaction when an atom is replaced by an isotope.
How are an atom an element and an isotope different from each other?
An element is a class of substances An atom is the smallest possible piece of an element. An isotope is an electrically charged atom.
This atom is a of helium -4?
isotope
What is the same and what is the different for an isotope compared to an atom?
An isotope will have the same number of protons, but a different number of neutrons than a given atom.
How many neutrons are present in an atom of the isotope?
The number of neutrons will vary for every isotope of an atom and is not possible to generalize for all the elements.
