hiyaaaaa!!!!
i dunno but ne1 else but balancing covalent bond equations always throw me. can anyone explain to me how to do em wit an example please?????
thank u thank u
luv me!!!! :wave: :rofl:

not sure about what you mean by balancing covalent bond... i think it would be helpful if you provided an example of what you don't understand.

are you talking about the lewis dot thing?

umm .....say u had to do a compound of......Chlorine and Silicon. how wud u do this? i mean how wud u noe how many of each atom is needed?

If this was possible, we would consider how many electrons are in the covalent shell, and try and make stable shells of 8 electrons ...

uh huh....

I seriously doubt this is in the syllabus?

no it is a lil bit but theres no harm in noein it incase it mite pop in my face on one of my frequent trips to assessment task city. i gotta noe how to smak it down if i ever meet it.
(no i am not high).........maybe

octet rule: atoms love 8 electrons in outer shell
covalent bond: each bond allows a pair of atoms one extra shared electron

inert gases: 8 electrons => no bonds formed
halogens (F, Cl, Br, I): 7 electrons => one bond formed
oxygen group (O, S): 6 electrons => 2 bonds formed
nitrogen group (N, P): 5 electrons => 3 bonds formed
carbon group (C, Si): 4 electrons => 4 bonds formed
hydrogen: first shell is max 2 electrons: => 1 bond formed

So a compound with nitrogen and fluorine: N forms 3 bonds, F forms 1 bond, hence formula is NF3
