Was going through resonance topic, but got confused when it was asked to check for the most stable struture. The first rule is, Check for Octet of all atoms. But how to do that, its getting difficult at times. eg. What is the basic techniquie to count the electrons around atom. And those "+" and "-" charges indicates formal charges or what? Please help me clearify that. Thanks

See + sign means one electron has been taken from that atom and - means one electron has been given to that atom

 

and when theres a bond the atom has two electrons because one it had earlier and other because of sharing with adjacent atom(COVALENT BOND)..

 

If its nt clear post the question again with where u hav the doubt i will clear it

BEST OF LUCK!!!!!!!!!!!!!!!!
