While I work on practice problems, in particular Lewis diagrams, always when I check my answer either I placed a bonding pair when it wasn’t necessary or even sometimes I put lone pairs but in the answer it shows that the lone pairs have been substituted to bonding pairs.
I am not going to show you all the problems that I make this mistake with, but it happens soo frequently. It gets especially annoying when I am trying to find the formal charge because my answer turns out to be incorrect, or when I have to find the electron pair geometry or the molecular geometry, when I am given only a compound. This is soo annoying and confusing.
Can you please give me a tip to master Lewis diagrams and not to make this mistake anymore.
Thank you
