Archeologists and geologists use half-life to date the age of organic objects in a process known as carbon dating. At the time of death organisms stop producing carbon 14.Since half life is a constant, the ratio of carbon 14 to nitrogen 14 provides a measurement of the age of a sample.In the medical field, the radioactive isotope Cobalt 60 has been used for radiotherapy to shrink tumors that will later be surgically removed, or to destroy cancer cells in inoperable tumors.

Once the basics have been mastered as they are presented here, those two pages will add an extra level of understanding to this topic.

These dot diagrams are made for neutral atoms, meaning atoms that have the same number of electrons as protons.

These steps result in workable electron dot diagrams, which are also called Lewis Dot Diagrams.

For a more detailed discussion see electron subshell filling and the electron dot diagrams based on that approach.

The half-life of a radioactive substance is a characteristic constant.
