Fe, P, O Ionization energy is the energy required to remove an electron from an atom in the gas phase. The ionization energy of gold is 890.1 kJ/ mol. Is light with a wavelength of 225 nm capable of ionizing a gold atom (removing an ...Cesium was discovered in natural mineral waters in 1860 by R. W. Bunsen and G. R. Kirchhoff, using the spectroscope they invented in 1859. The name comes from the Latin word caesius, meaning “sky blue,” which describes ...Consider the following approximate visible light spectrum: Barium emits light in the visible region of the spectrum.
