Electrons in Atoms

The atomic emission spectrum for an element

• is continuous (like the rainbow).

• shows all possible frequencies.

• shows the frequencies emitted by that element.

• is the same for all elements.

The atomic emission spectrum [check all that apply]

• is unique.

• can be used to identify an element.

• is explained by the particle model of light.

• is the same for all elements.

What is a flame test used for?

• Explain the wave nature of electrons.

• Determine which elements are NOT in a compound.

• Identify element(s) in a compound.

• Show the visible spectrum.

When an element shows its atomic emission spectrum,

• only specific frequencies of light (colors) are emitted.

• a continuous spectrum is emitted.

• all possible frequencies are emitted.

When atoms absorb energy, specific frequencies of light

• are absorbed and show as black lines in the absorption spectrum.

• are emitted and show as discrete colors.

• show as a spectrum of continuous colors.

When atoms of elements emit energy, it shows as

• black lines in the absorption spectrum.

• the atomic emission spectrum of that element.

• photons of specific frequencies (colors) being emitted.

• the ground state of the element's electrons.

A quantum of energy is the

• particle of electromagnetic radiation.

• atomic emission spectrum for an element.

• maximum amount of energy that can be gained or lost by an atom.

• minimum amount of energy that can be gained or lost by an atom.
