Cherries Posted May 9, 2018 Report Share Posted May 9, 2018 (edited) Does the number of delocalized electrons equal the number of valence electrons for an atom? Thank you! Edited May 9, 2018 by Cherries Reply Link to post Share on other sites More sharing options...
kw0573 Posted May 9, 2018 Report Share Posted May 9, 2018 In metallic bonding, each atom contributes however number of electrons to offset its charge. For example, 2+ is a common oxidation state so many metals contribute 2 electrons to the sea. Since in SL you are limited to main group metals, that just so happens to be their number of valence electrons, ie the number of the group. But for the transition metals it would be their oxidation number, instead. Reply Link to post Share on other sites More sharing options...
kw0573 Posted May 9, 2018 Report Share Posted May 9, 2018 I revised my answer and reposted above. Technically metals are neutral so it's the oxidation number not charge. For example Al would contribute 3 electrons to offset its oxidation number of +3. 1 Reply Link to post Share on other sites More sharing options...
