The following ball-and-stick molecular model is a representation of the amino acid alanine (unshaded spheres = H).Only the connections between atoms are shown;multiple bonds and nonbonded electrons are not indicated. -In order to complete an electron-dot structure of alanine,the oxygen atom labeled O₂ needs A)1 additional bond and 1 nonbonded pair of electrons. B)1 additional bond and 2 nonbonded pairs of electrons. C)1 nonbonded pair of electrons. D)2 nonbonded pairs of electrons.
