Title: How to tell if molecules like CH4 are nonpolar/polar, covalent/ionic? Post by: askollmeyer on Sep 19, 2012 Is there a way to tell if its polar covalent, or nonpolar covalent without a periodic table?

you have 4 C-H bonds, a C-H bond is covalent C can make 4 bonds therefore, with 4H bound to 1C, the H atoms must be as far apart as possible from each other. non-polar molecule, covalent .....H H - C - H .....H |
