Francium, with atomic number 87, does not have the highest atomic number. When it was discovered, in 1939, scientists already knew of five elements with higher atomic numbers: radium (88), actinium (89), thorium (90), protactinium (91) and uranium (92). By the end of 2015, the highest atomic number was 118 - for ununoctium.
