Figure 21-12 shows four situations in which five charged particles are evenly spaced along an axis. The charge values are indicated except for the central particle, which has the same charge in all four situations.

Chapter 31: Atomic Physics Line spectrum of hydrogen: a series of individual lines caused by light being emitted by a lowpressure gas when subjected to a large electric field. Wavelengths in the visible spectrum of hydrogen are given by the following equation: 1 =R 1 − 1 λ (2) n2 where n = 3, 4, 5,… and where R is the Rydberg constant 1.097 x 10^7 m^(1) Assumption of Bohr’s Model of the Hydrogen atom: o The electron in a hydrogen atom moves in a circular orbit around the nucleus o Only certain orbits are allowed, where the angular momentum in the nth allowed orbit is nh L= 2π o Electrons in allowed orbits do not radiate. Radiation is emitted when an ele
