Question 3 What is wrong with the following orbital spin diagram? tt 1s O One arrow should be in the 1s and one arrow should be in the 1p. One arrow should be pointing up and one arrow should be pointing down. O The 1s has two orbitals so one arrow should be in the first 1s orbital and the other arrow should be in the second 1s orbital. O Both arrows should be pointing down, not up.
