Polonium has the highest atomic number in group 6A, a.k.a. group 16 on the Periodic Table. Its atomic number is 84. Polonium was discovered by Marie Curie, and she named it after her home country of Poland. All isotopes of polonium are radioactive.
Some newer periodic tables will show another element below this one, ununhexium (Uuh, atomic #116) but this is still up for debate.
The elements on the periodic table are arranged in order of increasing atomic number.
The periodic law states that when the elements are arranged by increasing atomic number, there will be periodic repetition.

In a given period, group 18 elements will have the highest atomic number.
The element provisionally named ununoctium, believed discovered in 2003, has atomic number 118 in Period 7, column 18, with an atomic weight of 294. Once confirmed, it will be given its permanent element name.
