Short hand notation of Ag

Allison:

Adovbush:

Ya I got no clue what chu talking about lol I'm out sorry

Gdeinward:

I have a bit of knowledge in this, but what is it that your having trouble with?

Allison:

I don't know how to answer it lol

Gdeinward:

well short hand notation is really asking you to summarize the electron configuration

Gdeinward:

here check did article https://socratic.org/questions/what-is-shorthand-notation

Gdeinward:

it wants to know the short hand notation of argon, witch is the symbol for the previous noble gas, and the additional electron configuration for argon

Allison:

[Ne] ??

Gdeinward:

your on the right track,

Allison:

Then add 8

Allison:

[Ne] 1s2 2p6 ?

Gdeinward:

no

Allison:

Yikes

Gdeinward:

take the electron configuration for Argon 1s22s22p63s23p6

Gdeinward:

and take the electron configuration for Neon 1s2 2s2 2p6

Gdeinward:

Since Argon contains the configuration for Neon, you can subtract it from Argon to leave 3s23p6

Allison:

[Ne] 3s2 3p6

Allison:

OHHHHHHHHHHHHHHHHHHHHhhhhhhhhhhhhhhhhhhhhhhhhhhhhh

Gdeinward:

correct

Allison:

HEHE I got it, thank youuuu <3

Allison:

Ag isn't Argon ahhhhhhhhhhhhhhhhhhhhhhh

Allison:

Ar is Argon

Allison:

Ag is silver

Gdeinward:

DAMN

Gdeinward:

just do exactly what we did with argon, but do silver XD

Allison:
