How can one find isotopes in a given sample?
Isotopes in a sample can be found using techniques such as mass spectrometry, which separates isotopes based on their mass-to-charge ratio, or through nuclear magnetic resonance spectroscopy, which detects isotopes based on their magnetic properties. These methods help identify and quantify the different isotopes present in a sample.
How can one determine which isotope is most abundant in a given sample?
To determine the most abundant isotope in a sample, scientists use a technique called mass spectrometry. This method measures the mass-to-charge ratio of isotopes in the sample, allowing researchers to identify the isotope that appears in the highest abundance.
How many half-lives would be necessary for a sample of parent isotopes to decay to the point that only one-half of the sample is composed of parent isotopes?
It would take one half-life for a sample of parent isotopes to decay to the point where only one-half of the sample is composed of parent isotopes. Each half-life reduces the amount of parent isotopes by half.
How can one determine the relative abundance of isotopes in a sample?
One can determine the relative abundance of isotopes in a sample by using mass spectrometry, a technique that separates and measures the mass-to-charge ratio of isotopes in a sample. This allows scientists to calculate the relative abundance of different isotopes present.
How can one identify a lipid in a biological sample?
One can identify a lipid in a biological sample by using techniques such as chromatography, mass spectrometry, and nuclear magnetic resonance (NMR) spectroscopy. These methods can help separate and analyze the lipid molecules present in the sample based on their chemical properties and structures.

How do the isotopes of given element differ from one another?
isotopes of a given element differ in the number of neutrons they have.
What is the difference between sample and sample size?
a sample is a sample sized piece given... a sample size is the amount given in one sample
How did the mass spectrometer advance the periodic table?
Using mass spectrometer, one can identify and/or separate the isotopes of the elements and also predict its composition in a given mixture.
How many half-lives would be necessary for a sample of parent isotopes to decay to the point that only one-half of the sample is composed of parent isotope?
One half life.
Why is a closed system necessary in radiometric dating?
Because you determine the ratio between different elements or isotopes. When one of the elements you are looking at is either added to or removed from your sample, this ratio gets distorted, and you won't be able to make a correct guess of the age of your sample.

How can one accurately measure hydrogen in a given sample?
One can accurately measure hydrogen in a given sample using techniques such as gas chromatography, mass spectrometry, or titration. These methods involve separating and quantifying the amount of hydrogen present in the sample.
How can one identify an isotope?
Isotopes can be identified by their atomic number and mass number. Isotopes of an element have the same number of protons but different numbers of neutrons. This difference in neutron count results in different mass numbers for each isotope. Scientists use mass spectrometry to measure the mass of isotopes and identify them based on their unique mass numbers.
