I got a weird question in my chemistry book. It says Li and Cl react to form LiCl an ionic compound. Cl has .... electrons in its outermost occupied shell and the answer of the book is 6 electrons . How?

6$\begingroup$ Book is wrong. Chlorine has 7 valence electrons. $\endgroup$– orthocresolCommented Nov 18, 2015 at 19:26

1$\begingroup$ Unless of course the book meant the p-shells only and the resulting ion. Which would be weird as hell. $\endgroup$– JanCommented Nov 18, 2015 at 19:33

3$\begingroup$ @Jan - it would be p "subshell" then, although I wouldn't put it past a book that says chlorine has 6 valence electrons to mix up shell and subshell... $\endgroup$– orthocresolCommented Nov 18, 2015 at 19:36

Maybe your book is wrong. It can't be. There has to be 8 electrons in the outermost occupied shell and to complete its octet. I searched over the google about it and found three links to cover my answer.

2$\begingroup$ Chloride has 8 valence electrons, chlorine has 7. Btw, I don't think it's really necessary to cite sources for this kind of thing... but if you really want to cite sources, please try to choose more reliable sources. Even though people always like to say "Wikipedia is unreliable", it is not a bad start. $\endgroup$ Commented Nov 18, 2015 at 19:35

1$\begingroup$ @orthocresol that's why i chose to take three sources. How much probability is there that all three of them would be wrong. I would have commented them but due to lack of reputation points, i couldn't. $\endgroup$– manshuCommented Nov 18, 2015 at 19:38
