According to Plank's theory, for a given frequency, v, matter can emit or absorb energy only in ____ ____ ____ __ __.
Whole number multiples of hv
The ____ is the phenomenon in which electrons are emitted from a metal's surface when light of a certain frequency shines on it.
T or F - Like the visible spectrum, an atomic emission spectrum is a continuous range of colors.
T or F - The fact that only certain colors appear in an element's atomic emission spectrum indicates that only certain frequencies of light are emitted.
T or F - The neon atoms in a neon sign emit their characteristic color of light as they absorb energy.
Bohr's model of the atom predicted the ___ of the lines in hydrogen's atomic emission spectrum.
According to Bohr's atomic model, the smaller an electron's orbit, the ____ the atom's energy level.
According to Bohr's atomic model, the larger an electron's orbit, the ____ the atom's energy level.
Bohr proposed that when energy is added to a hydrogen atom, its ____ moves to a higher-energy orbit.
According to Boh'rs atomic model, the hydrogen atom emits a photon corresponding to the difference between the ____ ___ associated with the two orbits it transitions between.
Bohr's atomic model failed to explain the ____ of elements other than hydrogen.
Atomic emission spectrum
______ ____ ____states that it is impossible to know both the velocity and the position of a particle at the same time.
Heisenberg's uncertainty principle
____ ____ ____ originally applied to the hydrogen atom, it led to the quantum mechanical model of the atom.
