ground state

Postby Matt Sanruk 2H » Wed Oct 23, 2019 10:20 pm

I am still confused on how to do electron configuration for atoms in the ground state.

The ground state is the stabilized state, the opposite of excited state. I always use the noble/inert gas to represent the inner electrons and write out the valence electrons. For example, the electron configuration for Chlorine is [Ne]3s2 3p6.

Ah I see so this is very similar to the high school way of doing electron configuration, but with a fancier name. Is there any difference from high school chemistry that I should know?

There's one difference I noted when Dr. Lavelle talked about the periodic trends. He lectured about electron affinity but didn't mention electronegativity; I searched them up and found out they're different concepts: electron affinity is the energy released when electrons are added to gas-phase atoms, while the latter is the ability of an atom to attract electrons from outside. This was a little confusing to me at first, hope it helps.

I would suggest you print or create a blank electron configuration worksheet with boxes for each orbital, subshell, etc (like the first part of this website >> https://sites.google.com/a/usd411.org/c ... 2a/notes/k). You will be able to see how each elements electron configuration is "made". You will understand concepts like Pauli Exclusion Principle, Hund's Rule, spin states, quantum numbers, valence electrons, etc from this.

It is easiest to just know where the s, p, d, and f orbitals are. From there, you just go in order of the periodic table and count chronically in terms of how many electrons are in each orbital.

For ground state does every orbital need to have at least one electron in it before pairing , otherwise its excited?
