Characteristics of Atomic Spectra

The characteristic bright-line spectrum of an element is produced when electrons

• are given off as beta particles

• are gained from another atom

• move to higher energy levels

• fall back to lower energy levels

The characteristic bright-line spectrum of an atom is produced when

• nuclei of atoms undergo fission

• nuclei of atoms undergo fusion

• electrons move from higher to lower energy levels

• electrons move from lower to higher energy levels

When the electrons of an excited atom fall back to lower levels, there is an emission of energy that produces

• beta particles

• alpha particles

• spectral lines

• gamma radiation

The characteristic bright-line spectrum of an atom is produced by its

• electrons absorbing quanta

• electrons emitting quanta

• protons absorbing quanta

• protons emitting quanta

The characteristic bright-line spectrum of sodium is produced when its electrons

• return to lower energy levels

• jump to higher energy levels

• are lost by the neutral atoms

• are gained by the neutral atoms

The characteristic bright-line spectrum of an element is produced when its electrons

• form a covalent bond

• form an ionic bond

• move to a higher energy state

• return to a lower energy state

The characteristic spectral lines of elements are caused when electrons in an excited atom move from

• lower to higher energy levels, releasing energy

• lower to higher energy levels, absorbing energy

• higher to lower energy levels, releasing energy

• higher to lower energy levels, absorbing energy

What causes the emission of radiant energy that produces characteristic spectral lines?

• neutron absorption by the nucleus

• gamma ray emission from the nucleus

• movement of electrons to higher energy levels

• return of electrons to lower energy levels

The characteristic bright-line spectrum of an element is produced when electrons

• absorb quanta and return to lower energy levels

• absorb quanta and move to higher energy levels

• release quanta and return to lower energy levels

• release quanta and move to higher energy levels

The light produced by signs using neon gas results from electrons that are

• moving from a higher to a lower principal energy level

• moving from a lower to a higher principal energy level

• being lost by the Ne(g) atoms

• being gained by the Ne(g) atoms
