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.)
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.
A molecule is not any kind of bond! Instead it has or contains bonds. The bonds in HCN are covalent but fairly strongly polar.
6.02 x 10 to the 23rd power (same as avagadros number)
bread, milk, butter, anything that is made of a mixture.
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.
- 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
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.

Cytochrome C is a highly conserved molecular homology possessed by many organisms. Any molecule used in common and especially common purpose is homologous.
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.
Molecules have no size limit.

Nitrogen molecule does not contain any unpaired electron in its molecular orbitals. Unpaired electron is needed to keep up the mechanism of burning.
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.
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.
