The group 1A and group 2A metals have some characteristic properties. The group 1A metals (alkali metals) have the lowest ionization energies of all the elements - they very readily give up their one (s) valence electron to form +1 cations. Alkali metals are also soft and have low density and low melting points.

Group IA. Period 6. Group 8A / Ra Groups are the vertical columns on a periodic table, and group 2A is on the left. Alkaline earth metals are group 2A, and they have two valence electrons. Metals (Group 1A Elements): Definition & Properties 6:38; Alkaline Eart The periodic table is structured so that elements with the same pattern of known as the alkali metals (group 1A) and alkaline earth metals (group 2A), are those  Solved: Without referring to a periodic table, write the name and give the symbol for one element in each of the following groups: 1A, 2A, 3A, 4A, 5A, 6A, 7A, 8A,  The periodic table displays the symbols and names of the elements, along with information about the structure of their atoms.
