Electron Configuration Help

Postby Lynsea_Southwick_2K » Fri Oct 26, 2018 9:47 am

The last time I have seen electron configurations I was a sophomore in high school, when we first saw them in lecture I was very lost. I have tried watching videos to teach myself about them and I thought I started to understand but I was confused again when it came to the shorthand way of writing it. I might even be overthinking it.

Can anyone refer me to video that helped them? Or does anyone have any tips?
Thanks.

Khan Academy is usually a good resource, maybe these would help:

I think in general, practicing writing out full electron configurations for different atoms/ions is helpful, to get familiar with the order of shells and orbitals.

There are a lot of videos that make these concepts simple on YouTube.

For electron configurations, literally, write down the number of electrons in each orbital of the atom.
For example,
Hydrogen has 1 electron and it's in 1s orbital, so the EC for that is: 1s^1
Lithium has 3 electrons, 2 in 1s orbital, 1 in 2s orbital, so EC for Li is: 1s^2 2s^1
Carbon has 6 electrons, 2 in 1s, 2 in 2s, 2 in 2p orbital, EC: 1s^2 2s^2 2p^2
