i need a answer goish just tell me Edit :: This looks suspiciously like a homework question. It wouln't be called the "Average Atomic Mass" if it wasn't the average of all the isotopes, now wouldn' it?

What tells you how heavy an element's atoms are compared with atoms of other elements?
This is the relative atomic mass, which compares other atoms to the mass of I atom of the isotope carbon-12.
What does the relative abundance tell you?
The concentration of each isotope of a natural chemical element.
What is the name of the instrument used to measure the relative abundance of an isotope?
This would be done in a mass spectrometer.
The relative abundance of each isotope of an element determines its?
The relative abundance of each isotope of an element is used to determine its atomic mass. This is the weighted average of all naturally occurring isotopes.
What is the weighted average of the isotope bromine?
Bromine's average eight is 79.904 is the answer in my reference, with more than 20 isotopes.
Why do chemist use relative masses of atoms compared to a reference isotope rather than the actual masses of atoms?
because, the mass of an atom is too small to be easily used as a point of reference. Comparing it to the C-12 atom (so relative Atomic Mass) is much easier. I think this is the answer.
How can the relative and absolute ages of rock be determined?
By comparing the relative percentages of a radioactive (parent) isotope and a stable (daughter) isotope.
What isotope of carbon has been chosen as the reference isotope for atomic mass units?
The atomic mass may be considered to be the total mass of protons, neutrons and electrons in a single atom (when the atom is motionless). Relative isotopic mass is the relative mass of a given isotope scaled with carbon-12 as exactly 12.
What tells you how heavy an element's atoms are compared with atoms of other elements?
This is the relative atomic mass, which compares other atoms to the mass of I atom of the isotope carbon-12.
What is the relationship between radioactive isotope and radioactive dating?
In radiometric dating, the amount of a certain radioactive isotope in an object is compared with a reference amount. This ratio can then be used to calculate how long this isotope has been decaying in the object since its formation. For example, if you find that the amount of radioactive isotope left is one half of the reference amount, then the amount of time since the formation of the object would be equal to that radioactive isotope's half-life.
Why must radioactive decay must be constant in order for radiometric dating to be accurate?
Amount of certain radioactive isotope in an object is compared with a reference amount. this ratio can then be used amount.
Why must radioactive decay must be constant in order for radioactive dating to be accurate?
Amount of certain radioactive isotope in an object is compared with a reference amount. this ratio can then be used amount.
Explain why radioactive decay must be constant in order for radiometric dating to be accurate?
If radioactive decay rates were not constant, the passage of time inferred from radiometric dating would be inaccurate. Changes in decay rates would affect the ratio of parent to daughter isotopes used in dating, leading to flawed age calculations. The fundamental assumption of radiometric dating is that decay rates remain constant over time.
How do you find relative atomic mass?
By relating carbon 12 isotope
What is is relative abundance?
The concentration of each isotope of a natural chemical element.
What isotope of carbon has been chosen as the reference isotope for atomic mass unit?
carbon 12
Explain how radiometric dating is used to estimate absolute age?
Radiometric dating is based on the principle that certain isotopes decay at a constant rate over time. By measuring the ratio of parent isotopes to daughter isotopes in a rock sample, scientists can calculate how much time has passed since the rock formed. This method provides an accurate estimate of the absolute age of the rock or fossil.
