Answer:

Well we has got................

#7_"Cl"+2xx6_"O"+1_"negative charge"=20*"valence electrons"# to distribute across 3 centres...

Explanation:

And so....we gots #"chlorite ion"#, which distributes 10 electron pairs as required....(there are 2 lone pairs on the doubly bound oxygen....and of course the negative charge is delocalized....

en.wikipedia.org

The electronic geometry around chlorine is tetrahedral. The molecular geometry is bent with #/_O-Cl-O~=109.5^@# to a first approx.
