How does adding an atom affect the position of existing atoms or lone pairs? - ANS pushes them away from the newly added atom How does adding a lone pair affect the position of existing atoms or lone pairs? - ANS same as adding an atom, pushes them away from the newly added Are adding atoms/ lone pairs similar? - ANS yes, because all electrons repel each other How do the electrons in bonds (bonding domains) differ from lone pairs( non-bonding domains)? - ANS ...
