... and will change into other types of atoms. In an experiment, a physicist measures the mass of a plutonium atom to be 3.9516 x 10-25 kg. Later, she finds that the plutonium has changed into a Uranium atom with mass 3.8851 x 10-25 kg and a Helium atom with mass 6.6447 x 10-27 kg. Can you find somethin ...

SCIENTIFIC NOTATION
... In science, you will often encounter very small and very large numbers. The mass of an atom of gold, for example is 0.000000000000000000000327 gram. A gram of hydrogen contains 602,000,000,000,000,000,000,000 hydrogen atoms. Writing and using such small or large numbers is very cumbersome. You can w ...
