Energy levels

When writing the hybridization of an atom such as Borirn in BF3, is it necessary to write the energy level (2sp2) or can we just write it as (sp2)

I know that as you go towards the bottom left of the periodic table, the radii of the atoms will increase and the ionization energy decreases, but are there any exceptions to the trends? If there are, should we be worried about knowing which ones are the exceptions or is it best to just consider the...

I understand what the spin number is and how it can only hold two values -1/2 and 1/2. I am just curious to know how to tell what the value the electron takes is. Is it only possible to tell through experimentation (the magnetic field experiment discussed in lecture) or is there a way to tell from t...

The first comment about covalent bonds is correct. For the rest you would need a periodic table. (You’ll need one for covalent just to check if its a nonmetal)
