the electron in the hydrogen atom can move about the nucleus only in __________ orbits

energy levels

specific orbits in an atom in which electrons move

quantized

restricted to certain values

ground state

lowest energy state of an atom

excited states

stable

fill in the blank

the lowest energy state possible is the most _________

quantized

fill in the blank

both absorptions and emissions are ____________

matter waves

waves exhibited by any particle in motion; cannot move at the speed of light

electron microscopes

used to obtain sharp images of very small objects

wave-particle duality

fill in the blank

the ______-­_________ __________ of nature applies to all waves and all particles, though for macroscopic objects the wave properties are too small to measure and are ignored

wave-mechanical model

model of an atom that proposes that an electron in an atom behaves as a three-dimensional matter wave

standing wave

wave that oscillates in place, without overall wave movement or transfer of energy

uncertainty principle

principle stating that it is impossible to simultaneously determine the momentum and the position of an electron with certainty

max born

who created the born interpretation?

orbitals

regions of space through which an electron moves with probabilities determined using the Schrodinger equation

electron-cloud model

model of the atom in which values from the schrodinger equation are interpreted as the probabilities of finding an electron at a certain point in space

schrodinger

fill in the blank

born’s interpretation is simply another way of looking at the results of the ____________ equation
