K-Chem 5.7: Electron Configuration- Excited vs. Ground State

Is there a way to tell if an atom is in the excited state or the ground state just by looking at its electron configuration? Of course there is! Let’s learn how.

Thank you so much, that is really helpful. My exam is tomorrow and this is like last minute study xD

[Chatwaheart]

thank you! love your way of teaching. very clear

[AliAbbas-tihb]

Great video! Just totally loved it, very easy to understand the concept

[celestial]

Very concise and easy to understand. Thank you so much. :)

Im really confused with what he said at 3:20, he just said that we don't add or remove any electrons then he's saying to tell if the configuration is excited, we count the total # electrons and if its the same it ground, if its not, its excited. So then how does that make sense?

Thank you for updating！This video helps a lot

Why do you put 4P after 4S when what comes next is 3D?

Hi i was just wondering what the excited state for lithium and sodium would be

[syedakhudsiyatarannum]

how do we find the FIRST excited state electronic configuration

[chakradharbarman]

How to identify an excited electronic configuration that also violates the Hunds rule

Hi, thank you for the video! I would also like to ask... is it possible for excited state of lithium to be 1s2 4s1? I would normally say it'll probably be 1s1 2s1 2p1 but I am wondering if it can reach much higher energy state.

what is the excited state of arsenic? can it be 3d9 4p3 5s1

[MatheusGHenz]

I'm currently reviewing for my Stem achem ter and I don't get how the atoms emit color what color they'll emit... Could you explain?

[Vulecro]

Can electron jump to different types of orbitals?

[pavankalyan-ziei]

sir if a atom is excited than its atomic radius also increases?

[jackkai]

Not very true, to determine valid electron configuration of excited state atom you should also consider that the electron you're relocating should not follow the AUFBAF principle but rather MUST become in a higher energy level .
