Give the number of protons, neutrons and electrons in one atoms of 238U. An ion! And so we say that oxide ions have a charge of -2, and chemists (who are lazy) write this as O 2-. Who of the proclaimers was married to a little person? It is also the number written as a superscript to the left of the isotopic symbol (e.g. The oxide anion has a charge of #2-#. #""^16"O")#.
