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.
No, never. An isotope has to do with the nucleus of the atom.
Neutron
an isotope is defined by an atom with the same number of protons, but a different number of neutrons
an isotope
Yes it is. It is an isotope of the atom / element tin.
No, never. An isotope has to do with the nucleus of the atom.
Yes, they usually are; being an isotope does not change the chemistry of the atom.
An alumimium atom is electrically neutral and it is an isotope of aluminum.
An isotope shares the atomic number with its element atom. How does it differ from the element atom?
Neutron
An element is a class of substances An atom is the smallest possible piece of an element. An isotope is an electrically charged atom.
an isotope is defined by an atom with the same number of protons, but a different number of neutrons
An isotope will have the same number of protons, but a different number of neutrons than a given atom.
The number of neutrons will vary for every isotope of an atom and is not possible to generalize for all the elements.
an isotope
Yes it is. It is an isotope of the atom / element tin.
When an atom of an element has a different number of neutrons.
