from Organic Chemistry

Besides 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 ...

CHEMICAL BONDING AND MOLECULAR STRUCTURE

chemical 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
