Polonium is a radioactive element with a melting point of 254 degrees Celsius and a boiling point of 962 degrees Celsius. At 20 degrees Celsius, polonium would be in a solid state, as it is well below its melting point. In its solid state, polonium is a silvery metal with a cubic crystal structure.
Polonium is a solid, man-made, radioactive poor metal.
Polonium is a solid at room temperature. It is a rare and highly radioactive metalloid element that has a silvery-gray appearance.
Boron is a solid metalloid element with unique physical properties. It is hard and brittle with a blackish-brown color. Boron has a high melting point and is a poor conductor of electricity at room temperature.
The element Polonium was named by Marie Curie, who, with her husband, discovered it, for Polonia, or Poland. Mme Curie was born in Poland.
