What is the fundamental difference between covalent and ionic bonding?
A. In a covalent bond, the partners share a pair of electrons; in an ionic bond, one partner accepts electrons from the other.
B. In covalent bonding, both partners end up with filled outer electron shells; in ionic bonding, one partner does and the other does not.
C. Covalent bonding involves only the outermost electron shell; ionic bonding also involves the next electron shell inside the outermost shell.
D. Covalent bonds form between atoms of the same element; ionic bonds form between atoms of different elements.
