has two rows containing nearly one-quarter of all the elements. The first row is known as therare earth elementsorlanthanides. The secondf-block row is referred to as the actinides. The most common form of the Periodic Table, the Mendeleev-Seaborg form, has thef-elements at the bottom. ...

According to the periodic table, name the fourth element. List the symbols and names for two alkali metals, two noble gases, and two halogens. Name an element in the fourth period (row) of the periodic table with a complete outer shell. ...
The second row of the f -block elements are called actanoids (or, less desirably, actanides.The following names for specific groups in the periodic table are in common use:Group 1: alkali metals Group 2: alkaline earth metals Group 11: coinage metals (not an IUPAC approved name) ...
table. Guesses at the location of the enemy ships can be made by row and series labels for the elementally challenged, or better yet by element name. Hits and misses are marked with Xs and Os on the upper table, and play proceeds until that carrier hiding in the Actinide Archipelago is...
Well, the periodic table is periodic through the properties of the elements. If we go across a period of the table from the left to the right, the properties of the elements change drastically until we get to the end of the row. The next element is directly below the element we started...
according to the IUPAC. For instance, superheavy elements 113, 115, 117 and 118 wereverified by the IUPACin December 2015, completing the seventh row, or period, on the table. Several different labs produced the superheavy elements. The atomic numbers, temporary names and official names are:...
