chemistry.ucr.eduBesides their chemical bonds (bonding electron pairs), we show that N, O, and F have unshared electron pairs that are not in chemical bonds. The combined total of number of bonds and number of unshared electron pairs that we show equals 4 for C, N, O, or F. Since each chemical bond contains 2 electrons, our drawings of these molecules show 8 ...

ncert.nic.inchemical bonds. In the case of sodium and chlorine, this can happen by the transfer of an electron from sodium to chlorine thereby giving the Na+ and Cl– ions. In the case of other molecules like Cl 2, H2, F2, etc., the bond is for med by the sharing of a pair of electr ons between the at oms. In the pr ocess each atom
