The electron dipole moment of this particle is at most three times ten to the negative 26th, and would violate CPT-symmetry if it is non-zero. This particle has a half-life of 881 seconds, and can break up into a proton, an electron and an electron antineutrino via beta decay. This particle is composed of one (*) up and two down quarks, and nuclear fission is initiated by the bombardment of this particle. The number of this particle dictates what isotope an atom is, and they have mass roughly equal to that of a proton. James Chadwick discovered, for ten points, what particle found in the nucleus, which, as its name suggests, has a net charge of zero

First proposed by Lewis, it is related logarithmically to a gas's standard Gibbs free energy divided by the temperature and gas constant. At equilibrium, this quantity must be equal in both gas and liquid phases. Taking the derivative of the natural log of this function is equates it to the derivative of a reaction's chemical potential. Equal to the gas' pressure when the gas is ideal, FTP, identify this thermodynamic quantity which replaces partial pressure when working with real gases and describes the tendency of a substance to escape from its current phase, symbolized by f.

In one poem, this man recalls seeing a "witches' broth" of "assorted characters of death and blight/mixed ready to begin the morning right." Another of this man's poems, titled after a line from Macbeth, sees a young child fatally injured when a saw "leaped out at the boy's hand." This author of "Out, Out--" and (*) "Design" notes that "one could do worse than be a swinger of" the title trees in "Birches." He criticizes a man who claims that "good fences make good neighbors" in "Mending Wall." For 10 points, name this American poet of "Stopping by Woods on a Snowy Evening" and "The Road not Taken."
