Naming Bis Tris Tetrakis

For any compound with a changed prefix for example a compound like bis(ethylenediamine) instead of diethylenediamine would there ever be a case where you could have tris(ethylenediamine) or would it be tri-ethylenediamine. So i'm confused on whether or not you can combine tris with di or do you only...

Polydentate bonding

I'm slightly confused on how we know which element in a compound contributes to a mono-bi-polydentate ligand. And when we do find that how we should know if it is mono/bidentate. I.e. [CO3]2-

Expanded Octet

When do we know to use the expanded octet rule. For example in SO4 (2-) both the four single bonded and 2 single 2 double bonded lewis structures are correct just one is more stable. Is there a way of knowing when we should use an expanded octet?

Radicals and Biradicals

I understand the concept of radicals and bi radicals being an atom or multiple atoms having an single unpaired electron making the overall compound unstable. How would i know where to place the unpaired electron on a lewis structure? And how often do radicals and bi-radicals appear in nature?

Rydberg Constant

While reading through the textbook and some outside sources i came across different versions of the Rydberg constant
R= 3.28984*1015Hz
R= 13.605eV

When do you use each?and should we worry about the different units of R constant or do we only need the equation given in Hz?

Finding Orbitals from Quantum Numbers

How can you tell the number of orbitals given the quantum numbers n and l . There was a question where it is asked for the subshell notation and number of orbitals and I understand how to find the notation just not how to find the overall number of orbitals for the information given(Question 59 Page...
