Hi! What is the most ideal formal charge for a lewis structure?

Hi Ms. Pantula! I believe the answer to your question is zero because then it would be perfectly balanced.

For an atom, the most ideal, or most stable, formal charge would be 0.
For a multi-atom lewis structure, the most stable configuration would be the one with the least formal charges present. For example, one with an atom with a +1 charge and another atom with a -2 charge would be less stable than a structure with only one atom with a -1 charge

Hi! As the students above said, the most "ideal" formal charge for a lewis structure would be 0 as that would indicate that it is more stable than another lewis structure for the same molecule that may have a formal charge of -2 or any formal charge that isn't 0.

The formal charge that would provide the most stability for a lewis structure is one that is closest to the value of zero. A charge of -2 or -3 is farther away from zero, making a structure less stable than if it had a charge of -1.

Hi there!

Like everyone else said, the ideal formal charge of all atoms in a molecule would be 0. I believe my TA also mentioned that if you must have nonzero formal charges within your molecule, anything less/more than +-1 should be largely avoided.

The most ideal charge would be zero because it is most balanced and stable.

The ideal formal charge is 0 because that represents the structure is in balance. Think of a seesaw. If you have more weight on one side the whole thing tips. Same idea here where if even one element has a -2 charge while the other has +1 it won't be even and needs to fixed immediately.

Hi! as everyone has said, the ideal would be 0! just also wanted to add that that fact does not necessarily mean it's the most common form for every molecule or atom, even if it's the most stable. there are some molecules, as we've seen in class, for which one or more atoms do not have a formal charge of zero and the molecule is still common in nature!

Traditionally, you would want a formal charge of a zero. When thinking of a charge, I think of instability. When a molecule has formal charges, it means its atoms has a wonky number of electrons around themselves. If you have a formal charge of 0, that means that atom has the perfect number of electrons around itself.

Zero would be the most ideal formal charge because that is the most stable. When there is a formal charge on an atom, the electrons are not helping it be in a stable bond and thus lead to an unfavorable bond with the other atoms in a molecule. This does happen naturally, but ideally 0 would be the formal charge.

Like many others have said, the idea charge is zero, but this is not always possible. If possible, you want all the elements in a bond to have a formal charge of zero, but if the bond itself has a charge (as it has gained or lost an electron), then at least one of the elements will have a formal charge of some sort. In that case you want to get as many elements with a formal charge of zero as you can, and minimize the charge on the other elements.

The most ideal formal charge for a Lewis structure is 0. Otherwise it wouldn’t be stable. Hope this helps!

Hi! For an atom the most ideal formal charge is 0 as it much easier to keep charge within the same atom than spread it to another. However, 0 is not always possible so the charge closest to zero is the next best thing and net for a molecule 0 is also ideal.

Since the ideal formal charge for a lewis structure would be when it is the most stable, it would be 0.

The most ideal formal charge for a structure is zero. The farther away from zero the formal charge is, then the less stable it will become.

The ideal formal charge will always be zero because that is when the molecule is most stable/balanced.

Hello! Essentially, the most ideal formal charge for a Lewis Structure would be 0! This is because this will allow for the most stable configuration! The farther the charge is from 0, the more it becomes increasingly less stable. The way I like to think about this is by thinking about the word neutral. 0 is a neutral number that does not lean to one side more than another, it is balanced. I hope this helps!

The most ideal formal charge for a lewis structure is zero because that would mean that it is the most stable. The atom won't constantly be trying to either share the electron, give it away or gain any. In that case, it would be stable, living its life.

The most ideal formal charge would be 0 or whatever is closest to 0 because that would indicate the most stable formation.

Hello!!! The most ideal formal charge would be 0 because that means the atom is the most stable!! You would calculate the formal charge using the number of valence electrons minus the lone pairs plus the shared electrons over 2.

Hi,

The most stable formal charge would be 0 because it is not trying to gain or share electrons but its rather in its most stable form and has the amount of electrons that it desires.

The most ideal formal charge is zero, but sometimes it is not always possible to achieve zero in the lewis structures, so try to get as close to zero as possible.

The formal charge may not alwasy determine the idealism for a lewis structure, but more so the electron configurations that result from covalent or ionic bonds.

Because we want a balanced molecule, the preferably charge will be 0.

A molecular structure in which all formal charges are zero is preferable to one in which some formal charges are not zero. If the Lewis structure must have nonzero formal charges, the arrangement with the smallest nonzero formal charges is preferable. Lewis structures are preferable when adjacent formal charges are zero or of the opposite sign.

Hi Alekhya,

The most ideal formal charge for a Lewis structure is 0. Zero means it's the most stable and balanced. This also means that the charges closer to zero are more stable than the charges farther.

The ideal formal charge for a Lewis structure is 0, which indicates that the molecule/structure is stable.

The most ideal overall formal charge would be 0 with all the individual element formal charges also being 0. That would be the major resonance structure.
