How can electron exchange virtual photon with another electron when virtual particles live only for small time and distance between electrons can be bigger than distance photon can take in this time?

A better word than "live" would probable be the word "exist." And that leads to the question of what "exist" means.
When we say that electrons "exchange virtual photons," we do NOT mean that a particle with any measurable properties traveled from Point A to Point B with the speed of light. In a VAST over-simplification, the virtual photon never displays any measurable properites, and thus (in QM) doesn't really "exist" at any point during its travels.
Which leads to the obvious question, "Okay, so what DO you mean when you say that?" I wish I could give a simple answer. All I can do is refer you to the URL below, which discusses the use of virtual photons in long-distance interactions of particles.

Do inert elements gain electrons?
There is no electron exchange when no reaction takes place (this is what 'inert' means)
How do you remove an electron from an atom?
You dont remove an electron from an atom. Its kept there by the bonds of the atom. However, you can split an atom from an atom.
Is a molecule that has lost electrons been reduced?
OIL RIGOxidation Is Loss (of electrons)Reduction Is Gain (of electrons)So no, a molecule which has lost electrons has a positive charge and so has been oxidised
Which subatomic particle determines the chemical activity of an atom?
The electrons control the chemical properties of an atom. More specifically, the outer electrons, or valence electrons, are involved in bonding, and they determine the chemical properties of an atom.
What periodic group of elements does not ionize?
The Noble Gases (Group VIIIA or Group 8A) do not exchange electrons or become ionized into ions since they already have a full electron configuration.
How does a superconductor minimize its losses?
One feature of the universe is that energy can only be transferred (via exchange particles, or "virtual particles") in discrete units. In the quantum world, by definition, there is no such thing as "half" an exchange particle. In a normal conductor, the ambient heat, plus the energy of moving electrons, is enough to create exchange particles. These hit the conductor lattice and are turned to heat. (Emitting exchange particles is the quantum way particles "bump" off of things). In a superconductor, it is so cold, there is almost no thermal energy. There is no heat present to "help" with the creation of these exchange particles. When added to the energy of the electron's flow, there is still not enough energy to create an exchange particle, so the electron can't spend any energy. You could say that the electrons "bump" off the lattice, but nothing is exchanged, so the electrons continue on with the same amount of energy. The one exception is when the electrical current gets higher -- then, the increase electron energy can actually start creating exchange particles, which then create heat, which provides enough energy to help other electrons create exchange particles, and so-on, and whammo, suddenly you have a warm ex-superconductor.

Can any electron form a chemical bond?
Atoms form chemical bond. It is done by exchange of electrons.
How do you remove an electron from an atom?
You dont remove an electron from an atom. Its kept there by the bonds of the atom. However, you can split an atom from an atom.
The source of energy for the process of photosynthesis?
Electrons are used as an exchange currency during photosynthesis. The energy that provides the boost for these electrons comes from the electron transport chain.

The arrangement of electrons in an atom is called?
A unit of matter, the smallest unit of an element, having all the characteristics of that element and consisting of a dense, central, positively charged nucleus surrounded by a system of electrons. The entire structure has an approximate diameter of 10 -8 centimeter and characteristically remains undivided in chemical reactions except for limited removal, transfer, or exchange of certain electrons.
An electron exerts a force on another charged particle by?
The force exerted by charged particles is called a "coulombic" force.
What are the three subatomic particles in a atom besides protons neutrons and electrons?
Three subatomic particles found in atoms besides protons, neutrons, and electrons are up quarks, down quarks, and gluons. Up quarks and down quarks are the fundamental particles that make up the protons and neutrons found in atomic nuclei. Gluons are the exchange particles that transfer the information regarding the strong nuclear force between the quarks.
Can sodium and potassium combine to form a covalent bond?
no for a covalent bond requires an exchange of electrons and sodium and potassium only have one electron each and they cant lost it hope this helps someone :)
What periodic group of elements does not ionize?
The Noble Gases (Group VIIIA or Group 8A) do not exchange electrons or become ionized into ions since they already have a full electron configuration.
