I did those hw problems myself. All i ask you is to make sure if i did them corrctly by matching the questions with the answers. If i made a mistake please tell me where and how can i fix it thanks.

Questions: 12. Draw the orbital diagram for a ground-state nitrogen atom.

Answers

Which ground-state atom has an electron configuration described by the following orbital diagram? How many electrons are there in the 3rd principal energy level (n = 3) of a phosphorus atom? What element is represented by the electron configuration 1s22s22p63s23p63d104s24p64d105s1?

Explanation / Answer

hai dude you have done almost correct except that 3rd question. there they mentioned principal quantum number n=3. for phosphorous you have 3S and 3P orbitals so 2+3= 5 you will be having 5 electrons not 3... for all others you have done a great job.
