OK, we have two single electrons each and you have four so we can share all of ours and create CO2!
We are both non metals, so if you and your clone share your electrons with me, we can coavalently bond.
Hahaha, I'm the compound CO2, or carbonbioxide.
You are a true compound, but you'll need more to defeat me.
Carbon, if you could Ionicly bond and create H2O. You're a anion, which means you have a negative charge and I'm a cation, which means I have a positive charge. I can clone 1 more of me to match your -2 charge with a +2 charge. Then you will have a full octet.
