So-called communication

According to the metal supplier of powders, the nuclear number of pine forest equals 5, structure of an electron of valency of pine forest 1S22S22P1, 2S, an electron should activate easily to 2P an orbit to become an activation condition 1S12S12P2, to create three not connected electrons, pine forest covalent being linked orbital SP2, to create six trivalent structures of electronic structure of an angular body. P a rail is empty, electrons of valency of atom of pine forest it is less, than number of an electron of valency, in connection, electrons of valency are not full, atom of pine forest - electronic and imperfect atom, electronic and imperfect, thus having the essential, easily created key of the multicenter. So-called communication of the multicenter belongs, more atoms are necessary, less electrons unite a covalent delokalizatsiya of communication. For example, incorporated pair of electrons with three atoms, is known as communication with two electrons with three centers.
