Does it have a transition that absorb blue/green region? which one? Also, it is interesting that caesium metal (Cs) appears as a golden coloured metal, does anyone know whether this golden colour is due to a very minor oxidation of the metal or whether there is a physical basis for this...

The most common examples of metal hydrides include aluminum,boron, lithium borohydride and various salts. For example, aluminum hydrides include sodium aluminum hydride. There are a number of types of hydrides. This includes aluminum, beryllium, cadmium, caesium, calcium, copper, iron, lithium, magn...
How many hydrogen atoms, which measure 0.1 nm across, will fit across a single caesium atom with a diameter of 0.6 nm ? For Effective Nuclear Charge, I'm confused about why the electrons would want to get closer to the nucleus? What's the purpose of them getting closer?
Addition of 1 in THF at 200?K to a suspension of an excess (5.8 equivalents) of caesium graphite (CsC8), followed by warming, filtration, and solvent removal, afforded a dark‐green oily solid of unknown composition, from which several red–brown rhombohedral plates of the ditantalum salt ...
M is an alkali metal ion such as lithium, sodium, potassium, or caesium, particularly lithium, sodium or potassium, although metallic elements in the second row of the Periodic Table such as barium, magnesium or calcium may be useable, as may transition metals such as copper, iron or cobalt...
The red column is known as Group 1, and the orange column is Group 2. The elements in these groups are known as reactive metals. Pure sodium fizzes and shoots around when placed in water, potassium bursts into flame in water and caesium explodes when added to water! The reactivity of the...
