Four questions for you to answer :-)
Ques:
1) Electrons are arranged in pairs ( hence the electron pair repulsion theory) - why is this the case?
2) Why do all atoms try to fill their outer shells? Why are they most stable if their outer shells are full?
3) How exactly do atoms "share" electrons in a covalent bond? If the electrons are wizzing round nuclei how are they shared between the two atoms? Is it just a case of them spending some time around one atom and some around the other or is it something more complecated?
Thanks in advance. :-)
