So, the valence configuration of an antimony atom would be 5s2 5p3. The ground state complex quickly dissociates into unbound atoms: The result is an exciplex laser which radiates energy at 248nm, near the ultraviolet portion of the spectrum, corresponding with the energy difference between the ground state and the excited state of the complex. it is an akali metal, it has one electron in its outer shell, it forms a 1+ ion, it is very reactive. (This isotope has the second-longest known half-life among all isotopes for which decay has been observed; it undergoes double electron capture to 78Se). It is now known, however, that several of these elements are quite abundant on Earth and in the rest of the universe, so the designation rare is misleading. It can be extracted from liquid air by fractional distillation. The element was discovered in 1898 by the British chemists Sir William Ramsay and Morris W. Travers in the residue left after a sample of liquid air had boiled almost entirely away. Screened from the nucleus by intervening electrons, the outer (valence) electrons of the atoms of the heavier noble gases are held less firmly and can be removed (ionized) more easily from the atoms than can the electrons of the lighter noble gases. This makes their separation difficult. Krypton gas is also combined with mercury to make luminous signs that glow with a bright greenish-blue light.
