Within the diamond structure, the distance between any two electrons is larger than the distance between any electron and carbon nucleus, if f=kq1q2/r^2 stands.I cannot imagine such structure in 3d space. It seems logically impossible. What do you know/think? Thanks!
Presumably you are talking about conduction-band electrons?
How could electrons get to so close to each other under super strong repulsion force between them?
Let's take a look at gold atom, so many electrons around nucleus, how is another gold atom able to even get to closer? Any two au atoms should repel each other.

Neutral atoms do not attract each other electrostatically, the way ions would. However, especially with large atoms, like gold, there are still electrostatic forces that attract them (see London Dispersion Force: http://en.wikipedia.org/wiki/London_dispersion_force)If gold atoms get too close, they will repel (again electrostatics and Pauli exclusion)However, there is another attractive force that keeps the atoms together in solid or molten states of gold, where the atoms are very close to each other, but not close enough to repel strongly. This force is commonly referred to as "bonding." It is a quantum phenomenon that is responsible for all types of chemical bonding other than ionic bonds (as are found in salts like NaCl or Fe2O3. Essentially, electrons near nuclei can be described as occupying orbitals. These orbitals can be centered on a single atom, or distributed among several different atoms that are close to each other.Please see: http://en.wikipedia.org/wiki/Covalent_bond http://en.wikipedia.org/wiki/Molecular_orbital http://en.wikipedia.org/wiki/Metallic_bonding
It is worth pointing out that diamond does revert back to graphite (very slowly) when the pressure is released.
No scientist is dumb enough to give away the real secret of how to use carbon to make diamond.
How much pressure will be enough to push electrons into nucleus? Isn't between them is 99.9999% empty space and strong attraction force?
In graphite, each carbon atom is bonded to 3 other carbon atoms, and they are all in a plane. Each atom has two electrons that are as low in energy as they can get (1s orbital). The next highest in energy (3 electrons per atom) are shared between two neighboring carbon atoms (one can think of these as sigma bonds), and the highest energy electrons (1 electron per carbon) are free to exist anywhere in the lattice (one can think of these as an extended pi bond or a conduction band).Is this a joke? Who seriously believe it? Or it is the best model one can get?
Or is it the best model one can get?
Isn't force the mechanism for everything?
Besides pulling out quantum laws, no one has an logical answer to: What force keeps opposite charges apart as electron and proton in atoms?

All I care is the real structure of atoms, may carbon or gold or hydrogen.

Yes. If there were more or less, it wouldn't be carbon. And don't confuse theory with reality: science is not religion.
You can ionize carbon atoms with radiation. Up to six electrons can be removed, leaving a nucleus with a charge of +6. That is how we can experimentally verify there are six electrons.It is also a definitional thing. It is carbon because there are six protons in the nucleus. To be a neutral carbon atom, it must have six electrons.
