Stable and Unstable Isotopes Elements can be made up of different isotopes. Different Types of Radioactivity How is it measured?

Isotopes are atoms with the same number of protons and electrons, but a different number of neutrons. These are the elements that we see around us and find in nature. Radioactivity is measured using a unit called the "curie". The curie measures how many atoms spontaneously decay each second.

Anthropologists, archeologists, and paleontologists also use radioactive isotopes to date mummies, pottery, and dinosaur fossils. It is no more complicated than playing a dice game! Roll the Dice & Use Radiometric Dating to Find Out.

In this science project you will see for yourself by modeling radioisotope dating with a few rolls of the dice. Retrieved August 26, 2017 from https:// As humans, it seems easy for us to keep track of time lapses, as long as they range from a couple of seconds to a number of years.

Studying the Earth and its evolution, they work with time scales of thousands to billions of years. There are three main types of radiation or radioactive decay depending on the isotope. When isotopes are unstable they emit energy in the form of radiation.The curie was named after Marie and Pierre Curie who discovered the element radium. The half-life of an isotope is the time on average that it takes for half of the atoms in a sample to decay.For example, the half-life of carbon-14 is 5730 years.
