Collagen is also frequently used in bone grafts to help broken bones set and recover. Direct link to akhileshmulgund10's post Here, electrons and proto, Posted 4 years ago. Much of the study of chemistry, however, involves looking at what happens when atoms combine with other atoms to form compounds. The general rule is that "like dissolves like", which means polar molecules will dissolve into other polar liquids and nonpolar molecules will dissolve into nonpolar liquids. This is why oil and water don't mix: oil is nonpolar while water is polar. You can predict nonpolar molecules will form when atoms have the same or similar electronegativity. It is called amoleculeto the union of two or moreatomsby chemical bonds (of the same or different elements), forming a stable set. The exact properties of collagen differ depending on the tissue, though most types of collagen form tough fibrous strands give connective tissue mechanical strength and flexibility. Fullerene (a new allotrope of carbon) has $60$ atoms and is denoted by the symbol ${{\rm{C}}_{60}}$.
