According to Hund's Rule, if you were filling the three orbitals at the 2p energy level, you would first put an electron in the 2px orbital, then in the 2py orbital, and then in the 2pz orbital; and THEN use any additional electrons to pair up (one at a time) with those electrons.

True.

Explanation:

The Hund's Rule states that all orbitals must be singled occupied before any orbital is doubly occupied, and all the electrons at the singly occupied orbitals have the same spin number. By doing that, the electrons filled the lowest energy orbitals first.

The 2p level has 3 orbitals: 2px, 2py, and 2pz. So, when filling it, first put an electron in the 2px, then in the 2py, then and the 2pz (all with the same spin). After that, the remains electrons can be paired up.

According to Hund's Rule, if you were filling the three orbitals at the 2p energy level, you would first put an electron in the 2px orbital, then in the 2py orbital, and then in the 2pz orbital; and THEN use any additional electrons to pair up (one at a time) with those electrons.A. TrueB. False
