[quote=gensoh]...... .............oxygen | oxygen - chlorine - oxgyen err... uhmmm.. it dpends on the negative electron present on the element.. i think oxygen has 7.. and chlorine has 5.. therefore, connect each oxygen to the chlorine.. so that all oxygen will give one electron to the chlorine which makes chlorine to be stabled.. then add some dots on the oxygen.. (1/oxygen..) so that, oxygen will also have 8 electrons to make it stable.. u know the type of bonding... i think u know already wat i'm talking about..[/quote] ^I have something to clear. Is oxygen has 7 elctrons. I don't think so. It should be 6 electrons. and chlorine has 7 electrons. so, oxygen should give 1 elctron to the cholrine to make it stable.
