The energy states of atoms containing more than one electron arise from nucleus-electron and electron- electron interactions. Which of the following statements correctly describes these effects? O Larger nuclear charge lowers energy; more electrons in an orbital lowers energy. O Larger nuclear charge lowers energy; more electrons in an orbital increases energy. O Smaller nuclear charge lowers energy; more electrons in an orbital lowers energy, O Smaller nuclear charge lowers energy; more electrons in an orbital increases energy. O None...

According to Einstein's photoelectric effect, as long as the threshold frequency was met, brighter intensity light would increase the current of the cell. What was his reasoning for this? Brighter light contains more photons, all of which have enough energy to eject an electron from a given atom. Brighter light contains photons of higher mass that can hit electrons with more force, knocking them away from their atoms. Brighter light contains waves of larger amplitude which can hit more than...

22. Select the correct statements below. L. An atom of chlorine is larger than sulfur because the addition of an electron increases the repulsions without an increase in attraction for the nucleus resulting in less screening. An atom of oxygen is smaller than an atom of carbon because the distance of the valence electrons remains the same while the attraction for the nucleus increases with increasing number of protons. III. An atom of potassium is smaller than an atom of...
