Quizplus · Accepted Answer

The lowest energy level in an atom is called the ground state.

Answer: D
 Energy is a property of matter and is closely related to the electronic structure of atoms and molecules.

Answer: C
 An emission spectrum is a set of colors or wavelengths of light given off by an atom or molecule.

Answer: H
 The photoelectric effect is the phenomenon in which electrons are ejected from a surface when light is shined upon it.

Answer: I
 A photon is a particle of light.

Answer: K
 Photon emission occurs when an excited atom or molecule returns to a lower energy state by emitting a photon.

Answer: L
 The uncertainty principle is a concept in quantum mechanics that states that it is impossible to precisely measure certain pairs of physical properties, such as position and momentum, simultaneously.

Answer: M
 The wave function is a mathematical function that describes the probability of finding an electron in a particular region of space.
