Thus, when chromium is in the oxidation states +3 or +5, it behaves similarly to CrO. Chromium atoms that are in their ground state (+2) cannot form any compounds with oxygen; hence, there is virtually no oxidation of chromium in naturally-occurring alloys with magnesium or aluminum. ...
What is the Rutherford model of the atom? Discovery of the Atomic Nucleus: Rutherford discovered the atomic nucleus in 1911 when he attempted to pass a beam of alpha particles through a thin sheet of gold foil. Rather than passing through the sheet unimpeded, some of the alpha particles bounc...
