Question | Answer |
electromagnetic radiation | a form of energy that exhibits wavelike behavior as it travels through space |
wavelength | shortest distance between epuivalent points on continuous wave |
frequency | the number of waves that pass a given point per second |
amplitude | the wave's height from the origin to a crest, or from the origin to a trough |
electromagnetic spectrum | ecompasses all forms of electromagnetic radiation, with the only differences in the types of radiation being their frequencies and wavelengths. |
quantum | the minimum amount of energy that can be gained or lost by an atom |
Planck's constant | has a value of 6.626 X 10^-34 J X s, where J is the symbol for joule, th SI unit of energy |
photoelectric effect | photoelectrons are emitted from a metal's surface when light of a certain frequency shines on the surface |
photon | a particle of electromagnetic radiation with no mass that carries a quantum of energy |
atomic emission spectrum | the set of frequencies of the electromagnetic waves emitted by atoms of the element |
ground state | the lowest allowable energy state of an atom |
de Broglie equation | predicts that all moving particles have wave characteristics |
Heisenberg uncerainty principle | states that it is fundamentally impossible to know precisely both the velocity and position of a particle at the same time |
quantum mechanical model of the atom | the atomic model in which electroms are treated as waves |
atomic orbital | a three-dimensional region around the nucleus |
pricipal qhantum numbers | indicates the relative sizes and energies of atomic orbitals |
principal energy levels | atoms major energy levels |
energy sublevels | energy levels within principle energy levels |
