Please help me !!!
Your friend tells you that she has just read a report that scientists have synthesized the HeH- ion. Using what you know about MO theory, calculate the bond order of this ion. Based on the bond order, would you expect this ion to exist? Compare the stability of HeH- with that of HeH+. Use the MO diagram on the right for this problem.

I'm sorry but I didn't take higher level chemistry and this looks like it :/ Good luck
