Do isotopes determine the size or age of a rock?
age... parent and daughter isotopes in relation to half life
How do scientistes determine how meteorites been have in space?
By looking at radioactive isotopes. These isotopes decay at precisely known rates, so looking at ratios involving such isotopes can tell when an asteroid or other object formed.
Does neon have any isotopes and why?
Neon isotopes can be used in dating meteoric rock and to investigate the creation of some isotopes in space.
What is a way to determine age of fossil by comparing number of stable isotopes to number of unstable isotopes using half life?
Carbon decay or carbon dating
Do isotopes enable scientist to determine th size or age of some rocks?
age
Why did Meselson and Stahl use isotopes of nitrogen and not some other atom?
Meselson and Stahl used isotopes of nitrogen because DNA is made up of nitrogenous bases which are, as the name suggests, made up of nitrogen. I suppose they could have used phosphorus like Hershey and Chase did. But they are limited to the atoms that are present in DNA. There may be other reasons involved that would require digging up and taking into account of the the knowledge available in the 1950's (at that time).
How do scientists use isotopes to determine the of an object?
Scientists use the relative amount of stable and unstable isotopes in an object to determine its age.
What do isotopes enable scientist to determine?
age

How do you determine when isotopes are most abundant?
Isotopic composition is determined by mass spectrometry.

Is a way to determine the age of a fossil by comparing the number of stable isotopes to the number of unstable isotopes using a known half life?
relative dating

relative dating
Does neon have any isotopes and why?
Neon isotopes can be used in dating meteoric rock and to investigate the creation of some isotopes in space.
How do scientist determine How long have meteorites been in space?
By looking at radioactive isotopes. These isotopes decay at precisely known rates, so looking at ratios involving such isotopes can tell when an asteroid or other object formed.
