Atomic Spectra and Energy Levels

What is the primary cause of the emissions lines in atomic spectra

electrons transitions between energy levels

When does an electron move to a higher energy level

an electron moves to a higher energy level when it absorbs an amount of energy equal to the difference between energy levels

When an electron drops to a lower energy level, how is energy lost

Energy, equal to the difference between energy levels, is emitted as a photon when an electrons drops to a lower energy level producing light of that energy

How does the wavelength of low-energy photon compare to that of a high-energy photon

the wavelength of a low-energy photon would be longer than the wavelength of a high-energy photon

What does the atomic spectrum represent

The energy levels of electrons in an atom

Identify the photon in each pair with the greater energy
a. orange light or violet light
b. infrared light of ultraviolet light

a. Violet light
b. Ultraviolet light

What is emitted when an electron transitions from a higher energy level to a lower energy level

a photon

What does the term "excited state" of an atom refer to

electrons occupy high energy levels than normal

Electrons jump to higher energy when they ________ a photon

absorb

Electrons drop to lower energy levels when they ________ a photon

emit
