Group: group 2 (alkaline earth metals) Period: period 2: Block s-block: Electron configuration 2s 2: Electrons per shell: 2, 2: Physical properties; Phase at STP: solid: Melting point: 1560 K (1287 °C, 2349 °F) Boiling point: 2742 K (2469 °C, 4476 °F) Density (at 20 °C) 1.845 g/cm 3 [3] when liquid (at m.p.) 1.690 g/cm 3 : Critical point
Radium is the heaviest known alkaline earth metal and is the only radioactive member of its group. Its physical and chemical properties most closely resemble its lighter congener, barium. [4] Pure radium is a volatile, lustrous silvery-white metal, even though its lighter congeners calcium, strontium, and barium have a slight yellow tint. [4]

The chemical elements can be broadly divided into metals, metalloids, and nonmetals according to their shared physical and chemical properties.All elemental metals have a shiny appearance (at least when freshly polished); are good conductors of heat and electricity; form alloys with other metallic elements; and have at least one basic oxide.
Also agrees with Celsius values from Section 4: Properties of the Elements and Inorganic Compounds, Melting, Boiling, Triple, and Critical Point Temperatures of the Elements Estimated accuracy for T c and P c is indicated by the number of digits.
