Question

Show the electronic configuration from sodium through argon

Answer 1

Answer:

The p orbital can hold up to six electrons. We'll put six in the 2p orbital and then put the next two electrons in the 3s. Since the 3s if now full we'll move to the 3p where we'll place the remaining six electrons. Therefore the Argon electron configuration will be 1s22s22p63s23p6.
