Which of the following statements regarding electronic orbitals is/are correct?

Each p-orbital can hold a maximum of six electrons.

The 3p-orbitals have a higher energy level than the 3s-orbital.

The three 3p-orbitals have slightly different energy levels.

The 1s-orbital has the same size and shape as the 2s-orbital.

What is the Aufbau principle?

Within an energy level, s orbitals are the lowest energy, followed by p, d and then f. F orbitals are the highest energy for that level.

The lower the principal quantum number (n) the lower the energy.

All three.

The Aufbau Principle states that electrons enter the lowest energy orbitals first.

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.
