Which of the following statements is TRUE?
A) A covalent bond is formed through the transfer of electrons from one atom to another.
B) A pair of electrons involved in a covalent bond is sometimes referred to as a "lone pair."
C) It is not possible for two atoms to share more than two electrons.
D) Single bonds are shorter than double bonds.
E) In a covalent bond, the shared electrons interact with the nuclei of both of the bonding atoms, thus lowering their potential energy.

Question

Quizplus · Accepted Answer

In a covalent bond, the shared electrons interact with the nuclei of both of the bonding atoms, thus lowering their potential energy. Choice A is false because covalent bonds are formed through the sharing, not the transferring of electrons. Choice B is partially true, but a "lone pair" specifically refers to a pair of non-bonding electrons. Choice C is false as atoms can share even more than two electrons in certain circumstances. Choice D is false because double bonds are shorter than single bonds due to the increased electron density holding the atoms closer together.
