The isotope of an element is the different versions of that element. Due to the different number of neutrons. So the same element can have different numbers of neutrons in it's nucleus and therefore different mass numbers e.g. Chlorine 35 or Chlorine 37. Both contain identical numbers of protons but different numbers of neutrons.

∙ 11y agoAn isotope of an element is one whose atoms have the same number of protons as all of the atoms of the element, but a different number of neutrons. Mass number is the number of protons plus neutrons in the atomic nuclei of a particular isotope. An isotope is named for its mass number, such as carbon-12 and carbon-14 isotopes.

∙ 13y agoAn isotope of an atom is an atom which has a different number of neutrons in it's nucleus, therefore changing it's atomic weight.
(The number of protons and electrons stay the same.)

What is an atom called when the number of neutron changes?
an isotope of an element
What does the isotope of an element have?
An isotope of an element has a different number of Neutrons to the original element it came from. EG: Carbon( 11 neurtons) can go to carbon(12 Neutrons(
Does the atomic mass of an element depend upon the relative abundance of each isotope of the element?
Yes. The gram atomic mass of each element is the sum of the products of each stable isotope's isotopic fraction multiplied by the mass of that isotope.
What is the average atomic mass of an element is the average atomic masses of what kind of isotopes?
average atomic massof an element=(Atomic mass of first isotope X % of that isotope) + (Atomic mass of second isotope X % of the second isotope)
What is a parent isotope?
These terms apply to the decay of radionuclides. The parent isotope is 'the starting point' of a decay series that when it decays, by giving off radiation, changes into another element, or isotope of the original element (the daughter isotope). For example: When Uranium 238 (parent isotope) decays and gives off an alpha particle, it transmutes into Thorium 234 (the daughter isotope).
Why need to know the percentage of each isotope of an element to determine the atomic mass?
Because each isotope of an element has a mass different from any other isotope of the same element, and the atomic mass of an element is an average, weighted by the proportion of each isotope, in the naturally occurring element.
What is an atom called when the number of neutron changes?
an isotope of an element
What element has the atomic mass of 22?
An isotope of Neon. This isotope accounts for between a fifth and a quarter of the element.
What best describes a radioisotope?
its nucleus is unstable
What is an isotope of the element with 20 protons and 20 neutrons?
Yes, the isotope potassium-39 has 20 neutrons.
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 does the isotope of an element have?
An isotope of an element has a different number of Neutrons to the original element it came from. EG: Carbon( 11 neurtons) can go to carbon(12 Neutrons(
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.
Does the atomic mass of an element depend upon the relative abundance of each isotope of the element?
Yes. The gram atomic mass of each element is the sum of the products of each stable isotope's isotopic fraction multiplied by the mass of that isotope.
What is the average atomic mass of an element is the average atomic masses of what kind of isotopes?
average atomic massof an element=(Atomic mass of first isotope X % of that isotope) + (Atomic mass of second isotope X % of the second isotope)
What is a parent isotope?
These terms apply to the decay of radionuclides. The parent isotope is 'the starting point' of a decay series that when it decays, by giving off radiation, changes into another element, or isotope of the original element (the daughter isotope). For example: When Uranium 238 (parent isotope) decays and gives off an alpha particle, it transmutes into Thorium 234 (the daughter isotope).
What is the half-life of this element?
Without knowing the element and the specific isotope, this has no answer.
