How do you write the electron configuration of an element using the noble gas shortcut?
I know you have to go backwards to the noble gas nearest to the element and then you write [ ] and put the noble gas symbol in the brackets. The thing I don’t understand is how do you then write the electron configuration left?
Please give me an example for the element "silver".
Thanks. I’ll give 10 points to the most helpful answer.
You go back to the Noble Gas before it and use that configuration and just tack on, at the end, the part that was not included in that Nobel Gas’s configuration.
In silver, the configuration goes as follows:
1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 5s1
However, since the Noble Gas before it already contains the first half of the configuration (1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6), you just use the Noble Gas and add on the part that Noble Gas does not have. Which results in Ag’s configuration looking as follows:
[Kr] 4d^10 5s^1
