Max Planck
Term
Planck came to the conclusion that matter can gain or lose energy only in small specific amounts called _
Definition

Definition
neon gas
Term
True or false; in neon signs, neon atoms in the tube absorb energy and become excited. These excited and unstable atoms then release energy by emitting light.
Definition

Definition
atomic emission spectrum
Term
The ... of an element is the set of frequencies of the electromagnetic waves emitted by atoms of the element.
