Cracking the SAT Chemistry Subject Test

ELECTRON CONFIGURATIONS

For the SAT Chemistry Subject Test, you’ll have to be able to figure out electron
configurations. Here’s how:

Where   Does    Helium  Go?

Notice  that,   although

Helium  looks   like    it  should

be  in  the p   subshell    area,

it’s    actually    a   member  of

the s   subshell.   Make    sure

you memorize    that    as  well

as  your    general s,  p,  d,  and

f   subshells.
