A neutral lithium atom has three electrons. As you will
Chapter 37, Problem 37.68(choose chapter or problem)
A neutral lithium atom has three electrons. As you will discover in Chapter 41, two of these electrons form an inner core, but the thirdthe valence electronorbits at much larger radius. From the valence electrons perspective, it is orbiting a spherical ball of charge having net charge +1e (i.e., the three protons in the nucleus and the two inner-core electrons). The energy required to ionize a lithium atom is 5.14 eV. According to Rutherfords nuclear model of the atom, what are the orbital radius and speed of the valence electron? Hint: Consider the energy needed to remove the electron and the force needed to give the electron a circular orbit
