How many valence electrons are in ClO2. I think its 17...is it correct? Thanks.
17? I come up with 19, but you might want to double check that.
1 Cl = 1 x 7electrons each = 7e
2 O = 2 x 6 elecrons each = 12e
12 + 7 = 19
I see where I made my mistake. Are there 12 valence electrons in C2H6?
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.
14 is correct.
To determine the number of valence electrons in ClO2 (chlorine dioxide), you need to consider the electron configuration of each atom.
Chlorine (Cl) is in Group 7A or 17 in the periodic table. It has 7 valence electrons.
Oxygen (O) is in Group 6A or 16 in the periodic table. It has 6 valence electrons.
Now, to calculate the total number of valence electrons in ClO2, you multiply the number of valence electrons for each element by the number of atoms of that element in the molecule.
In ClO2, you have one chlorine atom and two oxygen atoms, so:
Total valence electrons = (Number of Cl atoms x Number of valence electrons in Cl) + (Number of O atoms x Number of valence electrons in O)
Total valence electrons = (1 x 7) + (2 x 6) = 7 + 12 = 19
Therefore, the correct answer is 19 valence electrons in ClO2, not 17.
