When conducting photoelectron effect experiments, if you increase the frequency of light (above the threshold frequency), what happens to the electrons being ejected from the metal surface? -the rate of electrons being ejected increases
-The rate of electrons being ejected decreases
-The kinetic energy of the electrons increases
-The kinetic energy of the electrons decreases
Both the kinetic energy and the rate of electrons being ejected increases.

Use the periodic table to determine the electron configuration of dysprosium (dy) and americium (am) in noble-gas notation.
