The law of octaves states that every eighth element has similar properties when arranged in order of increasing As a rule, the lower oxidation state becomes more stable as we go down a column of the periodic table. Lead, for example, is more likely to be found in the +2 oxidation state than tin. Thus, while tin reacts with oxygen at high temperatures to form SnO 2 , lead forms PbO. 1A 8A 2A 3B 4B 5B 6B 7B 8B 11B 12B 3A 4A 5A 6A 7A element names in blue are liquids at room temperature element names in red are gases at room temperature element names in black are solids at room temperature Periodic Table of the Elements Los Alamos National Laboratory Chemistry Division 39 * ** As 39.10 85.47 132.9 (223) 9.012 24.31 40.08 87 Periodic Table Quiz Name_____ Section_____ On the following table, fill in the names and symbols for the atoms in the first 3 rows (across) and the first 2 and last 2 columns. 1A 2A 3A 4A 5A 6A 7A 8A Periodic Table.

However, trends also exist within each group.

The periodic table, also known as the periodic table of elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties.The structure of the table shows periodic trends.The seven rows of the table, called periods, generally have metals on the left and nonmetals on the right.

Rows of elements are called "periods" and columns of elements are called "groups" (1A, 2A 3B etc.). The modern periodic table is sometimes expanded into its long or 32-column form by reinstating the footnoted f-block elements into their natural position between the s- and d-blocks, as proposed by Alfred Werner in 1905. Unlike the 18-column form, this arrangement results in "no interruptions in the sequence of increasing atomic numbers". Mendeleev's 1871 periodic table and Meyer's 1870 periodic table put thallium in its current position in the boron group and left the space below caesium blank.) [21] However, thallium also displays the oxidation state +3, [10] : 28 which no known alkali metal displays [10] : 28 (although ununennium, the undiscovered seventh alkali metal, is predicted to possibly display the +3 oxidation state).
