Noble Gases in Electron Configurations

Postby emaad_3H » Sun Oct 20, 2019 9:17 pm

Why do we use noble gases to shorten the electron configuration description of multi-electron atoms?

I believe it is simply for the convenience of shorthand notation.

Hello,

We use this as a shortcut so we don't have to write so much! My high school chem teacher always said chemists are lazy, if there's an easier way to do something, they'll do it :)

Noble gases are more stable, so that is why we use the closest noble gas to write the shorthand electron configuration. It just makes it easier to write out the configuration when we use the shorthand method using the noble gases.

In addition to what everyone else said, I think it's because the noble gasses don't react much and are very stable, much like the innermost electrons that they represent.

We are able to use the noble gases as a shortcut when writing out the configurations because they are perfect octets, meaning all of their orbitals have paired electrons. Since this is true, you can start at whatever the noble gas right before the element you are writing the configuration for on the periodic table and then build off of that since you are basically starting with the next empty orbital down the list. Hope this makes sense!

Kinda off-topic, but why are they called "Noble Gases"?
