right in full notation, and core

Full
Ca 2+ =
1s2 2s2 2p6 3s2 3p4

Core
Ca 2+ = [Ar] 4s2 - what happens when the 4s2 cancells out?

Your full notation is wrong.

I'm not quite certain what your second question is in regards to.

Ca = [Ar] 4s2

If you have the element S2- you're electron configuration will be [Ar], while the element S is just [Ne] 3s2 3p4.

hmm. thats the thing, the positive ion throws me off.... im supposed to remove 2 electrons in this order P -> S -> D so originally i would have 2+ more on the last shell

Second question im supposed to write in Core Notation.

Your supposed to remove the electron from the highest occupied electron orbital which is the 4s2 orbital - what would you have as a result?

Core notation refers to the noble gas notation - it's nothing complicated once you figure out the first part the second should be made apparent.
