	When writing out descriptions of a particular [[nuclear species]], neutron number is rarely included, and is written in the lower right hand corner. Nuclear species with the same number of [[proton]]s but a different number of neutrons are called [[isotope]]s. They will have the same [[atomic number]] but different [[mass number]]; an example would be: <m>^{16}_{8}O_8</m>, <m> ^{17}_{8}O_9</m>, <m>^{18}_{8}O_{10}</m>. Neutron number is implied from the [[mass]] number and the atomic number since: ''N = A-Z~~''. So writing~~ <m>^{16}_{8}O</m>, <m> ^{17}_{8}O</m>, <m>^{18}_{8}O</m> is generally how these nuclear species are written and <m>^{16}O</m>, <m> ^{17}O</m>, <m>^{18}O</m> is sufficient since it's 'known' that O means [[oxygen]], which means 8 protons.

==PhET: Build an Atom==
The [http://phet.colorado.edu/ University of Colorado] has graciously allowed us to use the following PhET simulation. This simulation builds atoms from protons, neutrons, and electrons and tests knowledge of the periodic table. The simulation shows how the neutrons and protons must balance for the nucleus to be stable. Note how this simulation allows changing the atomic number and mass number.
