The Historical Development of Atomic Theory

Question 1

The photoelectric effect is the

Revolt · Accepted Answer

B: emission

Question 2

Describe how the Bohr model explains both of these observations.

Revolt · Accepted Answer

In the Bohr model, electrons can exist only in specific energy levels. When an atom absorbs energy, an electron jumps to a higher energy level. When it falls back to a lower level, it emits light. The wavelength of this light corresponds to the specific energy difference between the levels. Because every element has a unique set of energy levels, each element produces a unique emission spectrum.

Question 3

Which statements are true of the electron cloud model? Check all that apply.

Revolt · Accepted Answer

B: It is considered the modern atomic model.; C: It describes the probable locations of the electrons.

Question 4

The energy of the emitted electrons depends on the of the light.
