Answer:

Element Name: Ca
or
Electron configuration: [Ar] #4s^2#

I wasn't actually sure which one you meant.

Explanation:

Group two, period four, holds Calcium as Ca with an atomic number of 20.

If you needed the electron configuration, it would be #1s^2##2s^2##2p^6##3s^2##3p^2##4s^2#

and when you're abbreviating that, you take the last noble gas it had passed; Ar.

Then, fill in until you get to the Ca. Which would look like: [Ar] #4s^2#
