Francium By Keith Barclay

These four elements all melt at temperatures slightly higher than room temperature.

What state is francium at room temperature.

In the periodic table above black squares indicate elements which are solids at room temperature about 22ºc those in blue squares are liquids at room temperature and those in red squares are gases at room temperature. Francium is a chemical element with symbol fr and atomic number 87. Sublimation the transition of a substance directly from the solid to the gas phase without passing through a liquid phase. Relative atomic mass the mass of an atom relative to that of.

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. Francium is a solid at room temperature. Its melting point is about 27 o c and its boiling point is 677 o c but both have uncertainty due to high. It decays into radium 223 through beta decay or into astatine 219 through alpha decay.

Francium is a chemical element with the symbol fr and atomic number 87. Prior to its discovery it was referred to as eka caesium it is extremely radioactive. The temperature at which the liquid gas phase change occurs. Francium symbol fr and atomic number 87 a radioactive and reactive metal melts around 300 k.

Francium belongs to alkali group of the periodic table so its physical properties are similar with alkali group elements. Francium is the shiny metal in its pure state and exist in liquid form at room temperature rather than a solid. Due to the small amounts produced and its short half life there are currently no uses for francium outside of basic scientific research. It is the second most electropositive element behind only caesium and is the second.

Most of the metals are solids under ordinary conditions i e 25ºc 1 atmosphere of pressure etc with the exception of mercury hg element 80 which solidifies. Density g cm 3 density is the mass of a substance that would fill 1 cm 3 at room temperature. 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.
