In the periodic table of the elements, each column is a group. In chemistry, a group (also known as a family) [1] is a column of elements in the periodic table of the chemical elements. There are 18 numbered groups in the periodic table; the 14 f-block columns, between groups 2 and 3, are not numbered.
There are an almost infinite number of compounds that contain carbon due to carbon's ability to form long stable chains of C—C bonds. [ 16 ] [ 17 ] All organic compounds , those essential for life, contain at least one atom of carbon; [ 16 ] [ 17 ] combined with hydrogen, oxygen, nitrogen, sulfur, and phosphorus, carbon is the basis of every ...

The alkaline earth metals are six chemical elements in group 2 of the periodic table. They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). [1] The elements have very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure. [2]
