What do Lewis structures show? A. all electrons B. all but the valence electrons C. only valence electrons D. only electrons that are unavailable for bonding. ** I THINK THE ANSWER IS C...IS THAT CORRECT? **
i think it is a
Nope, that wasn't it. Thank you though:)
the lewis dot structure represents how many valence electrons occupy the outer most shell of an element. The number of valence electrons also determines an element's electronegativity (going up the periodic table and over to the right). You can find the number of valence electrons for all of group A's by looking at their group number (1-7) for group B's (transition metals), they usually only have 2 valence electrons.
Take carbon for example: It is in GIVA, so it will have 4 valence electrons. |dw:1418541394621:dw| An element can hold no more than 2 valence electrons per shell, and no more than 8 maximum valence electrons in the outer most shell.
Hence why the noble gases are the most stable
