How many valence electrons are in ClO2. I think its 17...is it correct? Thanks.

Answer 1

17? I come up with 19, but you might want to double check that.

Answer 2

1 Cl = 1 x 7electrons each = 7e
2 O = 2 x 6 elecrons each = 12e
12 + 7 = 19

Answer 3

I see where I made my mistake. Are there 12 valence electrons in C2H6?

Answer 4

C2H6 = 14 valence electrons

There are 4 valence electrons in a C, so in 2 C there is 8. H has only one.
8 + (1 x 6) = 14 v.e.

Answer 5

14 is correct.
