What determines the color of light	wavelength
The number of cycles or crests that pass through a stationary point in one second.	frequency
Produced by the sun, by stars and by certain unstable atomic nuclei on Earth.	gamma rays
A released photon of light containing the precise amount of energy that corresponds to the energy difference between the two orbits.	quantum
represents the probability maps that show a statistical distribution of where the electron is likely to be found.	orbitals

models that predict how atoms bond together to form molecules	bonding theories
the sharing or transfer of electrons to attain stable electron configurations for bonding atoms.	Chemical bond
the transferring of electrons	ionic bond
only shared electrons	covalent bond
used to predict the shapes of molecules	VSEPR theory
the geometrical arrangement of the atoms	molecular geometry
