For students, understanding the general architecture of the atom and the roles played by the main constituents of the atom in determining the properties of materials now becomes relevant.

This gives scientists a material they can examine to estimate how long it has been since something was last alive.

Radioactive dating involves looking at the amount of decay that has occurred in order to estimate how old things are. We have over 200 college courses that prepare you to earn credit by exam that is accepted by over 1,500 colleges and universities.

Scientists think about the half-life of certain organic materials and using this constant decay rate to figure out the exact age of a found object based on how much one radioactive substance (like carbon-14) has decayed. You can test out of the first two years of college and save thousands off your degree.
