Lewis Structure for Acetylide Ion
How do you know that there's a triple bond between the carbon atoms in the acetylide ion? I drew the Lewis structure with a single bond between the carbon atoms and it still had the right amount of total electrons. But I guess that's not the correct Lewis structure for this ion.

Re: Lewis Structure for Acetylide Ion
There are many ways to draw a structure and we have to figure out which structure is best. The two ways I go by are checking if it's the simplest structure and its formal charge. Remember, the closer the formal charge is to zero, the more stable that molecule/compound is, and the more likely it is to appear as that structure :)

Re: Lewis Structure for Acetylide Ion
Like Alexa said, the most effective way to figure out the best structure is with formal charges. When the formal charges are closer to 0, the molecule will be more stable. I think Lavelle showed an example of this in the Monday's lecture if you want a more in depth explanation. Hope this helps!
