 True False  The energy levels of all atoms are quantized.

 True False  Atoms can lose energy by emitting a photon.

 True False  Electron states are described by orbits, which indicate exactly where an electron is located in an atom. 

 True False  Energy travels through space in the form of electromagnetic radiation.

Answer 1

Electrons move in elliptical orbits around the nucleus of an atom. - False. They move in a random manner around the nucleus of an atom

The energy levels of all atoms are quantized. - True. Each energy level has a permissible energy associated with it.

Atoms can lose energy by emitting a photon. - True. When an electron moves from a higher energy level to a lower one, it loses energy and this is emitted as a photon of light.

Electron states are described by orbits, which indicate exactly where an electron is located in an atom. - False. One can not tell exactly where an electron is located at any given time.

Energy travels through space in the form of electromagnetic radiation.- True.
