Chemistry: a molecular approach chapter 7 with answers
Quantum-mechanical model - correct answers A model that explains the strange behavior of electrons.
Electromagnetic radiation - correct answers A type of energy embodied in oscillating electric and
magnetic fields.
Amplitude - correct answers The wave is the vertical height of a crest (depth of a trough).
Wavelength - correct answer sThe wave is the distance between adjacent crests (or any two analogous
points) and is measured in units such as meters ,micrometers, or nanometers.
Frequency - correct answers The number of cycles (or wave crests) that pass through a stationary point
in a given period of time.
Electromagnetic spectrum - correct answers Visible light makes up only a tiny portion of the entire
electromagnetic spectrum which includes all wavelengths of electromagnetic radiation
Gamma rays - correct answers The form of electromagnetic with the shortest wavelength
X-rays - correct answers Electromagnetic radiation with wavelengths slightly longer than those of gamma
rays
Ultraviolet radiation - correct answers Electromagnetic radiatiin slightly smaller wavelengths than visible
light
Visible light - correct answers Ranging from violet (shorter wavelength, higher energy) to red ( longer
wavelength, lower energy).
Infrared radiation - correct answers Electromagnetic radiation emotte from warm objects with
wavelengths slightly larger than thos of visible light
