What is incorrect about this orbital diagram?
Both arrows in the filled 2p box should be pointing the same direction
There is nothing incorrect with this diagram
In the there should only be 1 arrow in the first 2p box and one in the 2nd 2p box
All the arrows should be pointing the same direction.

In an element with the electron configuration of 1s22s22p2 Which subshell of electrons would have the highest ionization energy and why?
The electrons in the 1s subshell. These are core electrons that are the closest to the nucleus so they would have the highest electrostatic force
The electrons in the 2s subshell. After the 2p electrons are removed it the 2s electron have less repulsion from the 2p subshell and are more strongly attracted to the nucleus.
The electrons in the 2s subshell. These are core electrons that where shielding the 2p subshell from the nucleus. Once the 2 p are removed the atomic radius shrinks thus increasing the attractive force of the nucleus.
The electrons in the 2p subshell. The 2 electrons shown in the p subshell of the configuration complete the octet for this atom. It is in the noble gas configuration so all the atoms of this element are held onto as if they were core electrons
