PHSC 1002 Study Guide - Midterm Guide: Activation Energy, Pion, Covalent Bond
Document Summary
No because they are on same side of table. When two identical atoms covalently bond, they share the electron"s equally. This is due to the shared electrons not bing more attracted to one nucleus than the other. When two different atoms covalently bond, one will attract the shared electron more than the other. The ability of one atom to more strongly attract electrons is call electronegativity. The greater the difference in electronegativity, the greater the polarity of the bond. Even through the molecule is electrically neutral, one side is more negative and the other is more positive. There is not a clear distinction between covalent and ionic bonds. The father apart on the periodic table, the more polar and then more ionic the bond. When molecules have more than two atoms, the overall polarity change. Multiple dipoles can cancel each other out to make a nonpolar molecule.
