Through heat and pressure
Answer;
The above statement is false.
Explanation;
The correct statement would have been;
The half life of an element of an element is the amount of time is it takes for half of radioactive isotope to decay.
-Isotopes are atoms of the same element that have the same atomic number but different mass number. Radioactive decay happens when an unstable atomic nucleus of an isotope spontaneously changes to a lower-energy state and spits out a bit of radiation.
-Half life is defined as the time it takes for one-half of the atoms of a radioactive material to disintegrate or undergo radioactive decay.
