Rubidium

• - State​ ​of​ ​matter​ ​at​ ​room​ ​temperature​ ​is​ ​a​ ​solid.
  
  
• - Number​ ​of​ ​valence​ ​electrons​ ​is​ ​1.


• - Rubidium​ ​is​ ​a​ ​soft​ ​metal,​ ​silvery-white,​ ​and​ ​can​ ​be​ ​stretched​ ​out​ ​into​ ​wire​ ​without breaking (ductile).


• - Density= 1.532​ ​g/cm³.


• - Good​ ​Thermal​ ​and​ ​electrical​ ​conductivity.


• - Rubidium​ ​tarnishes​ ​when​ ​exposed​ ​to​ ​air,​ ​reacts​ ​with​ ​water​ ​to​ ​form​ ​corrosive​ ​rubidium, and​ ​is​ ​a​ ​flammable​ ​gas.


• - Rubidium​ ​is​ ​not​ ​essential​ ​for​ ​life.


• - Important​ ​use:

• - 1= special glasses

• - 2= photocells

• - 3= propellant in ion engines in a spacecraft



• - Research= analyzing​ ​amount​ ​of​ ​rubidium​ ​in​ ​cerebro​ ​spinal​ ​fluid.​ ​There​ ​is​ ​less​ ​rubidium​ ​in Alzheimer's​ ​patients.
