The following is part of a molecular orbital energy-level diagram for MOs constructed from 1s atomic orbitals.

(a) What labels do we use for the two MOs shown?

Hello everyone today. We are being given the following problem. What labels do we use for the two mos or molecular orbital shown that are part of the molecular orbital energy level diagram for molecular orbital is constructed from two S atomic orbital's. So we want to note that the s orbital's form orbital's known as sigma orbital's. So this symbol here represents sigma orbital's in sigma orbital's. We have higher energy and lower energy, so we have our higher energy and we have our lower energy. And so for higher energy, we represent this with sigma, but we put a little asterisk next to it and for our lower energy we represent it with just sigma. And so with this we have our final answer. I hope this helped. And until next time.
