Question
The of a photos of light is proportional to its frequency and proportional to its wavelength. energy, directly, inversely energy. inversely, directly velocity, directly, inversely intensity, inversely, directly amplitude, directly, inversely According to experiments concerned with the photoelectric effect, which of the following will increase the kinetic energy of an electron ejected from a metal surface? decreasing the wavelength of the light striking the surface. decreasing the frequency of the light striking the surface increasing the number of photons of light striking the surface 1 only 2 only 3 only 1 and 2 a and 3 Which of the following statements is incorrect? It is not possible to know the exact location of an electron and its exact energy simultaneously. The energies of an atom's electrons are Quantum numbers define the energy states and the orbitals available to an electron The behavior of an atom's electrons can be described by circular orbits around a nucleus. Electrons have both wave and particle properties. The Pauli exclusion principle states that no two electrons in an atom can have the same four quantum numbers. electrons can have either 1 1/2 spies. electron with opposing spies are attracted to each other. no two electrons in an atom can have the spin. twp electrons occupying the same orbital must have identical spins. Which of the following statements regarding subshell filling order for a neutral atom is/are correct? Electrons are assigned to the 4i subshell before they are assigned to the 3d subshell. Electrons are assigned to the 4f subshell before they are assigned to the 6d subshell. Electrons are assigned to the 4id subshell before they are assigned to the 5i subshell. 1 only 2 only 3 only 1 and 3 1, 2, and 3 For which of the following elements is the second ionization energy greatest? Mg Ca Li Sc Ti rules states that the most stable arrangement of electrons is that which contains the maximum number of unpaired electrons, all with the same spin direction. Hund's DeBroglie's Plank's Bohr's Which of the following elements has the least negative electron affinity value? H K Li NaExplanation / Answer
