For a metal at absolute zero, the inverse of this quantity is proportional to the local density of states at the Fermi level by the Fukui function. For 10 points each:
[10h] A principle proved by Parr and Chattaraj states that systems evolve to maximize what quantity at constant temperature and chemical potential?
ANSWER: chemical hardness [accept absolute hardness]
[10m] Chemical hardness is proportional to the difference between ionization energy and this quantity, which is multiplied by ionization energy in Mulliken’s definition of electronegativity.
ANSWER: electron affinity [prompt on affinity]
[10e] Chemical hardness extends hard–soft acid–base theory, which itself is built on this scientist’s conception of acids as electron pair acceptors.
ANSWER: Gilbert Lewis [accept Lewis acids or Lewis bases]
