Let us consider a molecule of carbondioxide.This is a covalent compound where the valence electrons of the oxygen and carbon atoms are fulfilled.

There are still 4 electrons for each oxygen atom in their outer shell.

so,where do these electrons can revolve around thier orbit if the bonded electrons block thier path?

ARE THOSE ELECTRONS IN THE OUTER ORBIT ACTUALLY REVOLVING?

(I'VE TAKEN THE SIMPLE COMPOUND FOR EXAMPLE U CAN TAKE WHATEVER COMPOUND U WANT)

 

 

 

 

clear my IGNORANCE.

Electrons do not orbit molecules like planets orbit the sun. They exist in probability clouds which are usually represented by lobes which look something like this:

 

The lobes represent a 99% probability of finding the electron within that space. A 100% probability lobe would be the universe.
