### formal charge

does an atom need to be bonded for it to have a formal charge?

### Re: formal charge

Yes, an atom needs to bonded. The formal charge equation includes the shared electrons that the atom has and the nonbonding electrons.

### Re: formal charge

Yes, because to calculate formal charge, you need to use both the number of lone pair electrons and the number of bonded electrons.

### Re: formal charge

To clarify further, formal charge is defined as the gain or loss of electrons of an atom when forming a covalent bond. Thus, an atom not forming a covalent bond could not have a formal charge.

### Re: formal charge

Yes because formal charge refers to the charge of a compound. You must calculate it using the number of bound and lone electrons, proving that a bond is needed.

### Re: formal charge

Yes since the formal charge is for lewis structures, and lewis structures are made to map the bonds of the atoms in a compound.

### Re: formal charge

Yes, it does. Formal charge is used to determine the assigned charge of an atom in a molecule specifically.

### Re: formal charge

Yes! Formal charges refer to the charges of bonded atoms when an electron is lost or gained in a covalent bond.

### Re: formal charge

Yes you definitely do because you need to use both the number of lone pair electrons and the number of bonded electrons when considering the formal charge on the element.

### Re: formal charge

Formal charge definition states that it is the charge of an atom in a molecule, so it must be bonded to other atoms. Also if the atom was not bonded then there would be an important part of the formula missing, and it could not be calculated.

### Re: formal charge

Yes because you have to take into account the number of bonded electrons an atom has in order to calculate the formal charge.
