These are (except for hydrogen) soft, shiny, low-melting, highly reactive metals, which tarnish when exposed to air.

Irregular trends suggest that factors are working against each other in determining a property (such as the density “discrepancy” between sodium and potassium).
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).

As we have seen, elements in a given group possess general similarities. However, trends also exist within each group. In this section we use the periodic table and our knowledge of electron configurations to examine the chemistry of the alkali metals and alkaline earth metals. FIGURE 7.18 Elemental The periodic table is structured so that elements with the same pattern of outer-shell (valence) electron configuration are arranged in columns. For example, the electron configurations for the elements in groups 2A and 3A are given in Table 6.4. We see that the 2A elements all have ns 2 outer configurations, while the 3A elements have ns 2 np A. 2A B. 3A C. 4A D. 5A E. 8A 14.
