12 3 dating with radioactivity

Since radioactive decay is a random process, the decay of a single nucleus may happen at any time but for many undecayed nuclei, the average decay rate is given by the decay constant, λ and it has the unit of [s.

Out of these three particles, protons and neutrons located at the center of the atom as a hard and dense part known as nucleus.

The rest of the part of atom contains negatively charged particles called as electron which balance out the charge of the protons and make the atom electrically neutral..

This nuclei with decomposed is called as parent nuclei and the product nuclei is termed as daughter nuclei.

Nuclei with radii that are within the range of the Strong force are stable.

The elements with atomic number greater than 82 are radioactive.

The is a measure of how quickly on average a radioactive nuclei will take to decay.

Decay products from a nucleus with spin may be distributed non-isotropically with respect to that spin direction, either because of an external influence such as an electromagnetic field, or because the nucleus was produced in a dynamic process that constrained the direction of its spin.
