What State Would Francium Be At Room Temperature

Find color of francium fr at room temperature or find color of different elements like aluminum barium boron brass bromine bronze cadmium calcium carbon.

What state would francium be at room temperature. Francium is most likely a solid at room temperature but this cannot be known for certain as it is impossible to gather enough francium in one place to test its physical and chemical properties. Its most stable isotope francium 223 originally called actinium k after the natural decay chain it appears in has a half life of only 22 minutes. Francium is a solid at room temperature. Relative atomic mass the mass of an atom relative to that of.

It s expected the element would be a shiny metal in its pure state like the other alkali metals and that it would readily oxidize in air and react very vigorously with water. It is considered to be a solid at room temperature 20oc although francium has a very short half life 22 miuntes so the heat and energy given off by its decay may mean it is technically a. Francium belongs to alkali group of the periodic table so its physical properties are similar with alkali group elements. The temperature at which the liquid gas phase change occurs.

Francium s most stable isotope francium 223 has a half life of about 22 minutes. Sublimation the transition of a substance directly from the solid to the gas phase without passing through a liquid phase. Due to the small amounts produced and its short half life there are currently no uses for francium outside of basic scientific research. It decays into radium 223 through beta decay or into astatine 219 through alpha decay.

Francium is the shiny metal in its pure state and exist in liquid form at room temperature rather than a solid. Prior to its discovery it was referred to as eka caesium it is extremely radioactive. Its melting point is about 27 o c and its boiling point is 677 o c but both have uncertainty due to high. It is the second most electropositive element behind only caesium and is the second.

Francium is a chemical element with the symbol fr and atomic number 87.
