WebUnder standard conditions radium is a silvery metal. It is very radioactive emitting light rays that cause it to glow in the dark. When exposed to the air it will quickly form a black coating by reacting with the nitrogen in the air. It also reacts readily with other elements and substances including water. WebThere are 118 elements in the periodic table, out of which 92 are natural elements and the remaining are synthetic elements.
