<span>The correct answer is 2. 37Ca.
The fastest rate of decay in radioisotope is 37Ca. Another name for radioisotope is radioactive of isotopes which are of given element.
The different number of neurons and the same number of protons are present on the same element with different isotopes. Radioisotopes are considered to have an unstable combination of neutrons and protons.</span>
