Three different resonance structures can be drawn for the sulfite ion (SO3^2-), where the double bond can be placed between sulfur and each of the three oxygen atoms.
Resonance structures refer to bonding in molecules or ions that cannot be correctly represented by a single Lewis structure. The Lewis dot structures show valence electrons.
Phenanthrene has a total of five resonance structures due to the movement of pi bonds within its aromatic rings. These resonance structures involve shifting pi electrons around the molecule to create different arrangements of double bonds.
The condition is called resonance. Resonance occurs when a molecule can be accurately represented by more than one Lewis structure, where the actual structure is a hybrid of the different resonance forms.

Resonance structures demonstrate one of the weaknesses of the Lewis structure. Molecules represented by a the Lewis structure either have single bonds, double bonds, or triple bonds. The multiple bonds can sometimes be drawn in more than one place. In reality, the multiple bond is averaged out over the molecule, so that all of the atoms may have a 1 1/2 bond or a 1 1/3 bond rather than a single or a double bond.
There are two resonance structures that can be drawn for O3 (ozone). This is because there is a double bond that can be delocalized between different oxygen atoms, resulting in two possible arrangements of bonds.

I hope so, beacuse thats what I'm putting

A resonance structure is an alternate way of drawing a Lewis dot structure for a compound. For some molecules, there are multiple ways to draw a Lewis dot structure that still satisfy the rules (for instance, having the correct total electron count and satisfying the octet rule on each atom).Benzene is a classic example where a resonance structure is used. See the Web Links to the left for a diagram of benzene's two resonance structures. Note that in both cases, there are alternating double and single bonds between the six carbons. What changes in the two structures is which bonds are single and which are double bonds. In reality, all the bonds in benzene are identical. They are neither single nor double bonds, but something like a "one-and-a-half bond."There is a common misconception that in reality the molecule is somehow alternating between the two structures. It is not.. This is extremely important to understand! Resonance structures are simply a tool to make up for the fact that Lewis dot structures are not the best tool for describing bonding in molecules (they are very good, just not perfect!). Using resonance structures is a kind of band-aid to patch up this shortcoming of Lewis dot structures (for a better representation of bonding, you must use molecular orbital theory which requires quantum mechanics!).So if the is not alternating between the two structures, what's going on?! In fact the molecule's structure is always the same. The actual bonding the molecule is a mixture of the different resonance structures all the time. To see this, you have to look at the different structures and imagine blending them together to give one single structure which has contributions from each structure. So the bonds in benzene are not going back and forth being single and double bonds. Not at all! Not even really quickly. Instead the bonds are ALWAYS this average bond which is a bit of both single and double.Note also that not all resonance structures contribute equally to what the molecule really looks like. For benzene, there are two structures, and the real molecule is a perfect mixture of both structures, 50% each. However, the are some molecules for which you can draw more than a dozen structures! In this case, you might have one structure that is dominant, and the real molecule's structure is close to that, and the other structures only contribute a little bit. In other words, the real structure is a weighted average of all the different resonance structures, but the weighting for each structure depends on the details of that structure, and some have very little weighting.How do you tell what structures are more important that other ones? Only if the structures are identical by symmetry, like for benzene, do they contribute exactly the same amount. Another way to say this is that if you can convert between two structures just by rotating the drawing around, they are the same by symmetry. However, sometimes they are not the same at all. Here is how you tell. A better resonance structure has the following properties:-- bond is maximized-- formal charges are minimized-- negative formal charges are carried by the most electronegative atomsThere is no way to predict exactly how much each structure will contribute (except when two are equal by symmetry). But you can put them in order based on the three rules above (and they are listed in order of importance).
Most plants have special structures on their leaves called stomates. Carbon dioxide is drawn into the leaf tissue through these pore-like structures.
