Review: Atomic Structure, Emission Spectra & Periodicity

Each element produces its own pattern of emission spectra lines because each element has its own distinct

• Speed of light

• Electron configuration

• Number of neutrons

• None of these

The color of emitted light with the LONGEST wavelength is

• violet

• green

• red

• indigo

The color of emitted light with the SHORTEST wavelength is

• violet

• green

• red

• indigo

The unknown emissions spectra belongs to the element

• Hydrogen

• Mercury

• Neon

• Sodium

Each element on the periodic table can be identified by its

• classification as a solid, liquid or gas.

• location on the table.

• ability to react to form compounds.

• unique spectral "fingerprint."

What subatomic particle is responsible for the spectral lines seen in emission spectra diagrams?

• electrons

• protons

• neutrons

In order to go from ground state to an excited state, an electron must

• emit energy

• absorb energy

• wiggle

When an electron returns to ground state from an excited state, the atom will

• emit energy

• absorb energy

• rotate

• wiggle

If an electron moves from n=4 to n=2 it ____

• absorbs energy

• releases energy

In which state does an electron have the least amount of energy?

• Excited state

• Ground state

• Orbital

• Bohr model
