🤓 Based on our data, we think this question is relevant for Professor Poehlmann & Waymouth's class at STANFORD.
bonding MOs → without an asterisk (e.g., σ1s)
antibonding MOs → those with an asterisk (e.g., σ1s*).
Group Valence Electrons
Be 2A 2 × 2 e– = 4 e–
+1 charge – 1 e–
Use the drawing of MO energy diagram to predict the bond order of Be2+ and Be2–. Do you expect Be2– to exist in the gas phase?
