A full answer would be very long and complicated and essentially useless to most people, so I'm going to give some hints. If the long answer would have made any sense to you, the hints ought to be enough.
Atoms are typically on the order of 1-2 Angstroms in diameter.
Covalent bonds are about 1 Angstrom for bonds to hydrogen, 1.5 Angstroms between non-hydrogen atoms.
VSEPR theory works pretty well.
If you need to figure out the sizes of a lot of molecules, you should get a molecular modelling program; I'm not really in that field anymore, so I can't make good recommendations, but I've put a link to a list of packages in the related links section. (I personally favor CHARMM, but it's not free, particularly if you want the Momany-Rone force field parameter set which is excellent for small molecules.)

What is molecular model?
It's a model of a molecule.The term is used for three somewhat different concepts. It can refer either to a physical model of a molecule, or to a computer model of a molecule, or to a theoretical "model" of molecular behavior. The three are somewhat related, but still distinct.
Is HCN ionic or covalent?
A molecule is not any kind of bond! Instead it has or contains bonds. The bonds in HCN are covalent but fairly strongly polar.
How many molecules of water are there in one molecule?
6.02 x 10 to the 23rd power (same as avagadros number)
What is a substance made up of the atoms of two or more elements?
bread, milk, butter, anything that is made of a mixture.
Why is oxygen molecule paramagnetic?
Answer 1) O2 molecule has two unpaired electrons which is only proved by Molecular orbitals theory (M.O.T). the M.O.T may be checked in any standard book of Inorganic chemistry.Answer 2) If you examine the orbital diagram for dioxygen, it contains a SOMO (Singly-Occupied Molecular Orbital) with 2 unpaired electrons. Dinitrogen does not have this. These unpaired electrons contribute to magnetism.
What is the mass of a single molecule of water?
- calculate the molecular mass of the substance from the atomic weights of the contained elements - 1 molecule gram of any substance contain 6,023 141 79.1023 molecules (Avogadro number) - mass of a single molecule is: Molecular mass in grams/Avogadro number
What is the molecular weight of cellulose acetate butyrate?
Typically 20,000 to 60,000. Cellulose is natural macro molecule without any specific size or molecular weight. The same applies to the esters of cellulose.
What is the enzymatic breakdown of any type of food molecule by the edition of a water molecule to each molecular bond?
pepsin

What are molecular homoligies?
Cytochrome C is a highly conserved molecular homology possessed by many organisms. Any molecule used in common and especially common purpose is homologous.
How do you calculate isomers of a sugar molecule?
The same way you calculate the molecular mass of any compound. Alternatively, if you know the mass of one isomer, you don't need to do any calculations. All isomers having the same formula have the same mass.
Is any molecule or atom has the size 3.23 angstroms?
Carbon dioxide
How many atoms can be in any one molecule?
Molecules have no size limit.
Is HCN ionic or covalent?
A molecule is not any kind of bond! Instead it has or contains bonds. The bonds in HCN are covalent but fairly strongly polar.
Why does nitrogen not support burning?
Nitrogen molecule does not contain any unpaired electron in its molecular orbitals. Unpaired electron is needed to keep up the mechanism of burning.
How many atoms are there in the molecule of phospherous P4?
The answer is four. The molecular formula of any element or compund gives you the number of atoms of each element in a molecule. For phosphorus the most common form is P4 . The molecules are tetrahedral with a P atom at each apex.
Is there any molecule which have no molecular formula but have a empirical formula?
get your question to a grammar checker. As a 13 year old i have spotted these mistakes and it is apaling to think that this stuff is actually considored english.
