Which of the following statements is false about stability and decay?

• The less stable the isotope, the quicker the sample decays.

• Scientists use the half life as an indicator of how stable a particular isotope is.

• The half life is equal to the time it takes for one-fourth of a sample’s neutrons to decay.

• The more stable the isotope, the slower a sample decays.
