A new row begins when chemical properties repeat. They have a strong tendency to donate their valence electron in the last shell to form strong ionic bonds. Finally, IUPAC assigns collective names (lanthanoids and actinoids) and group numbering (1 to 18) and has investigated the membership of the group 3 elements. Group 3 elements can react by losing 3 electrons. The densities of the Group 1 elements increase down the group (except for a downward fluctuation at potassium). Group 3-12: metals with varying reactivities. Atomic Number. The first three elements in Group 1 are Lithium, Sodium and Potassium and the three pictures below show the arrangement of electrons in their atoms. In astrophysics and nuclear physics, it usually refers to iron, cobalt, nickel, chromium, and manganese. See About the Periodic Table for information on how Group can be used to characterize an element.. Group 1: alkali metals, or lithium family; Group 2: alkaline earth metals, or beryllium family; Group 3: the scandium family The numbers indicate approximately the highest oxidation number of the elements in that group, and so indicate similar chemistry with other elements with the same numeral.

The highlighted elements of this periodic table belong to the alkaline earth element family. When the 3 electrons are lost, a full shell of 8 electrons is exposed, creating more stable conditions. Lithium is a solid only about half as dense as water and lithium metal is the least dense metal. These elements are metals. Very often these categories are marked by a background color in the periodic table. The IUPAC proposal was first circulated in 1985 for public comments,[2] and was later included as part of the 1990 edition of the Nomenclature of Inorganic Chemistry. For example, group 16 is also described as the "oxygen group" and as the "chalcogens". Group, in chemistry, a column in the periodic table of the chemical elements.
