Formal Charge

Postby Katherine Brenner 3H » Fri Dec 06, 2019 7:14 pm

When you calculate a formal charge and get 1- will that be a formal charge of +1 or -1 because it is an electcron?

It does not matter that it is a electron, it will be 1-

Formal charge is valence minus number of lines and dots, and you can get a negative or a postiive answer when you do that

The charge would just be the result that you get directly from your equation, which is -1 in this case. Just because it's an electron doesn't make a difference since the equation only applies to electrons and with that reasoning and the equation, there is no way we will ALWAYS get a negative number.

You would get 1- for this.

Regardless of the fact that it is an electron, it will be 1-.

Formal charge is calculating the oxidative state of the atom so whatever number you get is the actual charge of the atom. Just remember that a negative charge means an atom has more electrons than its ground state and a positive charge means that it has lost an electron.

Hi! Formal charge can be positive, negative, or neutral, and in this case it would be negative. Hope this helps!

It would be -1 then :)

It doesn't matter if its an electron, formal charge is the # of valence e's - (# dots) - (#lines) to put it simply. So if you get -1 when you do this, the Formal Charge would be -1.
