4.0 Points Question 1 of 9 0.5 Points The reactivity of an atom arises from A. The potential energy of the outermost electrons (valence shell). B. The sum of the potential energies of all the electrons. C. The energy difference between the s and p orbitals. D. The existence of unpaired electrons in the outermost orbitals (valence shell). E. The average distance of the outermost electron orbital from the nucleus. Answer Key: D Question 2 of 9 0.5 Points Why is a single hydrogen atom likely to react with other atoms? A. Hydrogen’s 1s orbital is half full, so sharing an electron with another atom completes the valence shell and increases the stability of both atoms. B. Hydrogen’s 1s orbital is half full, and sharing an electron with another atom increases the potential energy of the system. C. Hydrogen atoms have a positive charge and so are stabilized by interacting with negatively charged atoms. D. Hydrogen’s tendency to form bonds with other atoms is independent of the number of electrons in its orbitals. Answer Key: A Question 3 of 9 0.5 Points What determines if a reaction is spontaneous (happens without continuous  input of energy from the environment)?
