In some cases, the isotopes eject particles, primarily neutrons and protons.

The nucleus contains protons (tiny particles each with a single positive electric charge) and neutrons (particles without any electric charge).

Orbiting around the nucleus are electrons (tiny particles each with a single electric charge).

Try the problems out, then check your answer below. If an element has a half-life of twenty million years, and there is 6.25% of it remaining in a rock, how old is the rock?

In a certain rock, there is 1/16th of the original parent element, and 15/16th of the daughter element.
