Group 2 Elements: The Alkaline Earth Metals No image available The elements in the group include beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).They are kept in certain solutions such as oil to prevent reactivity with the air. Shashin Shah, founder of 3 billion Think Investments, believes Blocks stock can double in two years. The reaction of Group 1 metals with oxygen (a redox reaction) Group 1 metals: 4M (s) + O 2(g) > 2M 2 O (s) (M Li, Na, K, Rb, Cs). The oxides and hydroxides are white ionic solids. Hydrogen, Helium and few elements of the d and f-block. The reaction of sblock metals and oxygen & their oxide (O 2) chemistry. This group lies in the s block of the periodic table. If the last electron enters the s-orbital, it belongs to the s-block and so is the case with the others. The word "alkali" received its name from the Arabic word "al qali," meaning "from ashes", which since these elements react with water to form hydroxide ions. It includes Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Caesium (Cs) and Francium (Fr). Although often listed in Group 1 due to its electronic configuration, hydrogen is not technically an alkali metal since it rarely exhibits similar behavior. The alkali metals include: lithium, sodium, potassium, rubidium, cesium, and francium. Group 1: Hydrogen and the Alkali Metals Alkali metals are the chemical elements found in Group 1 of the periodic table. Typically, the s-block elements are reactive metals forming stable ionic compounds containing M+ or M2+ ions.
