What is incorrect about this orbital diagram?

• Both arrows in the 2p box should be pointing up

• There is nothing incorrect with this diagram

• In the there should only be 1 orbital in the first 2p box and one in the 2nd 2p box

• All the arrows should be pointing up.

After 3p orbital has been filled with electron, why the electron is added to the 4s orbital instead of 3d orbital?

• difference in shape of orbital

• the first ionisation is increasing across the period

• the first ionisation is decreasing going down the group

• due to orbital energy level
