Draw Bohr diagrams for covalent compounds?
Posted 09 November 2005 - 11:25 AM
An example of a covalent compound is H2O, its correct Bohr diagram is:
To show the "sharing" of electrons. The second energy level circle of O intersects the first energy level circles of H.
But how can I draw the Bohr diagram for N2 and CO2?
I attempted to draw the Bohr diagram for the covalent compound N2 but failed to do so.
The second one of the diagram below is my usual method of showing sharing, now I must do it like the H2O example shown above (i.e. without drawing circles) Can someone please help? I seriously don't understand how I can show sharing of electrons by making the orbits of 2 atoms to intersect........"6" electrons are involved in the sharing...there is no way to join the orbits together and show how the 6 electrons are shared...
Can somone please teach me how to draw Bohr diagrams for the covalent compounds?

my drawings although crude and rushed, shows that the 2 N atoms are sharing 3 pairs of electrons, which i placed in the overlap, same with the CO2 but this time all the C valence electrons are shared - the other electron pairs I place opposite because of electro-static repulsion, which is a convention that my teacher showed me but doesnt really make sense if you consider quantum mechanics... but there you go
