What did schrodinger's quantum mechanical model eventually show?

 1.Schrodinger's equation deals with the modern atomic theory. 
2. They are tested by many scientists. 
3. I am not sure on this one. 
4. It depends on the atomic weight of the boron. There are 5 protons for sure, but the number of neutrons depends on the isotope.

Cr(oh)3 -> cr(3+) + 3oh-

Hope the image of the frequency formula
