Bound Together.....
a: Covalent bond ~
b: nut and bolt
What: "A covalent bond is like a nut and bolt: atoms are attached firmly together by a specific bond and if that bond is broken, it takes energy to put it all back together again. On a macro scale, it means once your plastic toy or tool is busted, it's busted."
