The most electronegative atom, fluorine, is assigned a value of 4.0, and values range down to cesium and francium, which are the least electronegative at 0.7. First Ionization Energy of Tantalum First Ionization Energy of Tantalum is7.89 eV. ...
The alkali metals include sodium, potassium, rubidium, cesium, and rancium. Lithium is also the least dense of all metals. It has a density about half that of water. Credit for the discovery of lithium usually goes to Swedish chemist Johan August Arfwedson (or Arfvedson; 1792-1841). ...
