Question

A photon of which electromagnetic radiation has the most energy? (ultraviolet, infrared, x ray, or microwave)

What is the minimum energy needed to ionize a hydrogen atom in the n=2 energy state? (13.6 eV, 10.2 eV, 3.40 eV, or 1.89 eV)

An electron in a mercury atom drops from energy level f to energy level c by emitting a photon having an energy of.... (8.20 eV, 5.52 eV, 2.84 eV, or 2.68 eV)

A mercury atom in the ground state absorbs 20.00 electronvolts of energy and is ionized by losing an electron. How much kinetic energy does this electron have after ionization? (6.40 eV, 9.62 eV, 10.38 eV, or 13.60 eV).

In the currently accepted model of the atom, a fuzzy cloud around a hydrogen nucleus is used to represent the .... (electron's actual path, which is not a circular orbit, general region where the atom's proton is probably located, general region where the atom's proton is most probably located, or presence of water vapor in the atom).
