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.

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.
Formula of atomic mass?
The atomic mass of an element is the weighted average of the masses of its isotopes, taking into account their natural abundance. It is calculated by multiplying the mass of each isotope by its abundance percentage, then summing these values to obtain the atomic mass. Mathematically, atomic mass = (isotope mass1 * %abundance1) + (isotope mass2 * %abundance2) + ...
Is bicarbonate an isotope?
No, bicarbonate is not an isotope. Bicarbonate refers to the chemical compound with the formula HCO₃⁻, which is an anion formed from carbonic acid. An isotope, on the other hand, refers to different forms of the same element that have the same number of protons but different numbers of neutrons. Bicarbonate can contain isotopes of its constituent elements, but it itself is not an isotope.
What are the steps in the process of calculating average in atomic mass given data about the isotopes of an element?
To calculate the average atomic mass of an element, you need to multiply the mass of each isotope by its abundance (as a decimal), then sum these values for all isotopes of that element. This will give you the weighted average atomic mass. The formula is: average atomic mass = (mass isotope 1 x abundance 1) + (mass isotope 2 x abundance 2) + ...
The mass of the mixture of the isotopes for an element?
The mass of a mixture of isotopes for an element is a weighted average of the masses of each isotope, calculated based on the isotope abundances. The formula for calculating the average atomic mass is: (mass of isotope 1 x abundance of isotope 1) + (mass of isotope 2 x abundance of isotope 2) + ...
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

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
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
Isotope A has half-life of seconds and isotope B has a half-life of millions of years which isotope is more radioactive?
Isotope A is more radioactive because it has a shorter half-life, indicating a faster rate of decay. A shorter half-life means that more of the isotope will undergo radioactive decay in a given time period compared to an isotope with a longer half-life.

How many neutron in lithium?
Lithium has two isotopes. (An isotope is the name given to the different "flavors" of a given element that have different numbers of neutrons in their nuclei.) Here's the list: 6Li - 3 neutrons, and a stable isotope - represents 7.5% of natural Li 7Li - 4 neutrons, and a stable isotope - represents 92.5% of natural Li A link is provided.4
