What advantage of a ball-and-stick model over a structural formula?

A ball-and-stick model may make spatial relationships clear at a glance that would only be apparent to experienced people well able to visualize in 3D without one.
There's an example from my days in graduate school that I like to use. One of the research groups in the department had been trying to synthesize a certain highly substituted ring system, but had been unable to do so (they had gotten close, but never managed the last couple of steps). Let me remind you, these were people who held at the least a Bachelor of Science in Chemistry, under the direction of a Ph.D., so it's not like they were completely clueless.
And then someone had the notion to construct a model of the system. Whereupon they immediately gave it up as hopeless, because then they could see why it wasn't working: there simply wasn't room to stick those last few substituents on; they physically wouldn't fit.
Thinking in 3D is a very special skill, and it's not always trivial to keep all the permutations straight in your head; it's relatively easy to convince yourself "Yeah, but maybe if this were twisted that way" until a model is staring you in the face with two atoms that need to occupy the same space no matter how you contort the rest of the structure to avoid it.

Which model provides more information a chemical formula or a diagram of the molecule?
A diagram, or structural formula, provides more information than a chemical formula, because a structural formula also shows the arrangement of the atoms in the molecule.
How does the structural diagram of methane compare with the model?
As the structural diagram of methane has more chemicals in it, then the model.
What is a model that shows how the atoms are arranged in a molecule?
This is a structural model.
What drawings is a structural model of C3H8?
The structural model of C3H8 should include bold and dashed bonds to show different planes. Bold is used for coming out of the page or screen and dashed is used for going away.
How does a compounds formula differ from a model?
A compound formula shows which elements are in that compound and how many; whereas, a model shows the bonds that are involved.
Which model provides more information a chemical formula or a diagram of the molecule?
A diagram, or structural formula, provides more information than a chemical formula, because a structural formula also shows the arrangement of the atoms in the molecule.
Does Kolbe formula represent a compound?
No, I had this as a choice in a check all that apply question and it is a junk answer meant to trip you up. The ways are structural formula,molecular formula,empirical formula,space-filling model,ball and stick model. Cheers.
What is the structural model of the plasma membrane called-?
structural model of plasma membrane is called the selectively permeable membrane Structural model of the plasma membrane is called Fluid Mosaic Model.
How does the structural diagram of methane compare with the model?
As the structural diagram of methane has more chemicals in it, then the model.
What is a model that shows how the atoms are arranged in a molecule?
This is a structural model.
The structural formula of benzene is often represented as a what?
A five sided shape of the hexagon is used to represent and model a molecule of benzene. The hexagon will have alternating double lines (or a single double) to indicate the presence of its characteristic double (sp2) bond.

Does the network model has structural level dependence?
yes it is
Who proposed structural model of DNA?
Watson and Crick
What is the difference between a structural formula and a molecular model?
A chemical formula is the number of atoms in a substance, and is the same as a molecular formula (provided the substance is a molecule - if not, it has no molecular formula). A structural formula shows how the atoms are linked, and there are different interpretations of this: eg C3H8O2 is the chemical formula of 1,2 propan di-ol, which is the same as the chemical formula of 1,1 propan di-ol the structural formula however is CH2OHCHOHCH3 for 1,2 propan di-ol and CH(OH)2CH2CH3 for 1,1 propan di-ol. A displayed formula shows all the bonds: ........H..OH...H.............O-H...H...H ........|....|.....|..................|....|.....| ....H-C.-.C.-.C.-.H.....H-O-C.-.C.-.C.-.H ........|....|.....|..................|....|.....| ....H-O...H....H.................H...H....H 1,2 propan di-ol........1,1 propan di-ol ---------------------------------- Some chemicals, such as table salt, have no molecule. Thus, they only have chemical formula but not molecular formula. The chemical formula of table salt is NaCl. There are other salts, such as Na2SO4, MgSO4, etc. (If you hear people saying "the salt molecule has the formula of NaCl...", believe me, they do not know what they are talking about.) Some compounds exist as molecules- discrete entities, such as water. This kind of compounds have molecular formula. Water's is H2O. Structural formula? Never heard of.
