B.
In a covalent bond, outer electron orbitals are transferred; in an ionic bond, outer electron orbitals are shared.


C.
In a covalent bond, outer electron orbitals are shared; in an ionic bond, outer electron orbitals are transferred.


D.
In a covalent bond, valence electrons are transferred; in an ionic bond, valence electrons are shared.

Answer 2

Co, meaning share, valent meaning valence. Sharing valence electrons is a covalent bond. Ionic bonds turn the two atoms into an anion (-) and a cation (+). So the answer is A.
