Friedrich Wohler at berlin in 1828 isolated the beryllium metal.īeryllium generally occurs in the earth’s crust to the extent of 0.0002 Beryllium was discovered inġ798 by French chemist Nicolas-Louis Vauquelin. Of alkali metals are often insoluble in water ALKALINE METALSġ metals are less reactive than group 2 metals. Group 2 elements are called alkaline metals because they formĪlkaline solutions, hydroxides, when reacting with water and their oxides areįound in the earth’s crust. GROUP 2 OF THE PERIODIC TABLE Group 2 elements are: Br To show patterns in atomic radius, ionization energy, and electronegativity. Same group elements have similar properties and reactivity. Each group of elements having the same number of valence electrons. S-, p- and d-block elements of the periodic table are arranged into these columns The 18 vertical columns of the table are called Groups. There are also more specific groups like alkali metals, transition metals, rare metals, alkaline earth, halogens, and noble gases. There are multiple ways of grouping the elements but they are commonly divided into metals, non-metals, metalloids. In the periodic table of chemical elements, there is a group (also known as a family) is a column of elements. Side of the periodic table GROUPING METHOD Metals are on the left side and non-metal are on the right Horizontally in order of increasing atomic number and vertically according to In the periodic table, chemical elements are present in rows The seven rows of the table are called a periodic table. It is a tabular display of chemical elements, arranged in order of atomic number in rows so that elements with similar atomic structure and recurring chemical properties appear in vertical columns.
