	Encyclopedia: Period 8 element (Site not responding. Last check: 2007-10-21)
		A period 8 element is one of the chemical elements in the eighth row (or period) of the periodic table of the elements.
		A period 3 element is one of the chemical elements in the third row (or period) of the periodic table of the elements.
		Periodic tables The periodic table of the chemical elements, also called the Mendeleev periodic table, is a tabular display of the known chemical elements.

		Instead of symbols for eight elements, Figure 5.11 shows s in the first two boxes and p in the last six boxes, showing that the 2s and 2p sublevels are being filled as the electron configurations of the elements in these boxes are completed.
		Elements in the s and p blocks are known as representative elements or main group elements.
		Many of the properties of the transition elements are related to the fact that, in their electron structures, the occupied s and d sublevels of highest energy are very close in energy.

		However, as a period 7 element, francium is subject to a phenomena called the "lanthanide contraction".
		As a consequence, sixth period transition metals are about the same size as their fifth period counterparts.

		Element 114 was reported informally in January 1999 following experiments towards the end of December 1998 involving scientists at Dubna (Joint Institute for Nuclear Research) in Russia apparently using isotopes supplied by scientists at the Lawrence Livermore National Laboratory, USA.
		Currently, the identification of element 114 is yet to be confirmed.
		As only about three atoms of element 114 has ever been made (through nuclear reaction involving fusing a calcium atom with a plutonium atom) isolation of an observable quantity has never been achieved, and may well never be.
