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.
Francium belongs to alkali group of the periodic table so its physical properties are similar with alkali group elements.
Francium is a solid at room temperature.
Francium s most stable isotope francium 223 has a half life of about 22 minutes.
Density g cm 3 density is the mass of a substance that would fill 1 cm 3 at room temperature.
It is possible that francium may be a liquid rather than a solid at room temperature and pressure.
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.
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.
Its melting point is about 27 o c and its boiling point is 677 o c but both have uncertainty due to high.
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.
Prior to its discovery it was referred to as eka caesium it is extremely radioactive.
It decays into radium 223 through beta decay or into astatine 219 through alpha decay.
The temperature at which the liquid gas phase change occurs.
Francium is a chemical element with the symbol fr and atomic number 87.
Relative atomic mass the mass of an atom relative to that of.
