Isotopes have the same number of protons but a different number of neutrons. Different isotopes of a single element are on the same position on the periodic table of elements. The existence of isotopes was first suggested in 1913 by a radiochemist named Frederick Soddy.

early life or gas bubbles because they hold clues about the earth's ecology millionsof years ago and enable scientist to compare early life forms .
A pH meter
...electrons.Isotopes contain the same number of protons (hence, the same number of electrons) and electrons are what determine reactivity. 2nd answer : The isotopes have the same chemical properties because the electronic configuration of an element is same there fore isotopes posses the same chemical properties .
age
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.
Scientists use the relative amount of stable and unstable isotopes in an object to determine its age.
age... parent and daughter isotopes in relation to half life
Isotopes of Nitrogen gay but
scientists Can tell the difference between two isotopes of the same element because, isotopes of the same elements always have the same number of protons.
It helps determine the absolute ages of rocks
