Question #1900175
Which atom in the ground state contains one completely filled p orbital?
The question is: Which atom in the ground state contains one completely filled p orbital? The choices are: 1) Ne 2) O 3) He 4) Be The answwer key says the answer is choice 2)O. However, I got choice 1) Ne. The electron configuration for Ne is 1s^2 2s^2 2p^6 I don't understand why the answer is not Ne if the p orbital is filled ?? For O, the electron configuration is 1s^2 2s^2 2p^4 What did I do wrong? Thank you!
