Isotopes are different forms of the same atom with different numbers of neutrons. For example, normal carbon is carbon-12, which has 6 protons, 6 neutrons. Carbon-14 has 2 extra neutrons making it heavier. But they have the same numbers of electrons and so react and form compounds in the same way - so the formula of methane CH4 or carbon dioxide CO2 is the same. If you want to be very specific you can indicate the labeled position with a superscript, thus: 13CH4 or CH313CH2OH indicate methane with the carbon-13 isotope or ethane labeled with carbon-13 at the alpha position, respectively.

Formula of atomic mass?
It's just a weighted average. Multiply each isotope's weight by its percent abundance. Usually, one is much more prevalent than the rest, but not always. The sum of these numbers is the average molecular weight. The formula is: atomic weight = massa x fracta + massb x fractb +....massi x fracti where: massi = the atomic mass of an isotope of a given element fracti = the fraction of this isotope in the isotopic composition of a given element
What is make an atom isotope?
It is the neutron that makes changes in atomic nuclei to change them from one isotope to another. For any given element, that element will have a fixed number of protons. It is, after all, the number of protons that determine the elemental identity. But the number of neutrons in a given element can vary, and we use the term isotope to talk about which particular atom we're investigating. That is, we apply the term isotope to speak to an atom of a given element with a certain number of neutrons in its nucleus.
Can the half life of a radioactive isotope decrease as the isotope decays?
No, the half-life of a radioactive isotope does not decrease as the isotope decays. That half-life remains constant. It's the amount of the substance that decreases as the isotope decays.
What is the cost of isotope bone scan test in India?
The cost of an isotope bone scan test in India will vary. The cost depends on where the test is being given, insurance, and the physician.
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 formula to find the natural abundance?
In chemistry, natural abundance refers to the abundance of isotopes of a chemical element that is naturally found on a planet. Its formula is given as: abundance of isotope = average atomic weight of the element / exact weight of isotope.
If the isotope is given for calcium what is the formula?
An isotope has extra/fewer neutrons than the original atom. So if you know the isotope you can deduce the original atoms' formula.For Ca that would be:20 protons40 mass number
What determines the mass of an isotope?
The number of neutrons in the nucleus, the number of protons is the same for each isotope of a given element.
What is half life of a isotope?
The half life of an isotope refers to the rate at which a radioactive isotope undergoes radioactive decay. Specifically, it is the amount of time it takes for half of a given sample of a radioactive isotope to decay.
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.

Are atoms of the same elements the same?
yes. but only for a given isotope
Why do nuclear reactors require a fissionable isotope?
The fissionable isotope is required for the nuclear reactor operation. The fissionable isotope when fissions it give energy due to the mass difference according to Einstein formula E = mc2

When naming chemical formulas which ones get prefixes?
When an element's isotope is different than the common isotope or if it is relevant to the matter at hand such as in nuclear chemistry, the element is given a prefix in superscript to indicate its isotope
