Atomic model (matching) Flashcards
Louis de brogile
proposed that electrons should be considered as waves
orbit
an allowed path around the nucleus w/ nothing in between the paths
absorption
energy is + to an atom in order to move an electron from lower energy level to a higher energy level
Werner Heinsberg
determined that it is impossible to know an electron’s position and energy simultaneously
orbital
a region in the atom where there is a high probability of finding electrons
Albert Einstein
stated that while light has wavelike properties, it is also a stream of particles called photons (dual wave-particle nature)
Erwin Schrodinger
developed equations that solved for the energy of the electron precisely, and its probable location
excited state
a state in which an atom has absorbed an higher amount of energy that it has in its ground state
Quantum Theory
describes mathematically the wave properties of electrons
Niels Bohr
developed a model of the atom in which the electron can only circle the nucleus in allowed paths (orbits) and there is nothing in between.
emission
an electron falls to a lower energy level, and a photon is emitted
ground state
the lowest energy state of an atom
Max Planck
Proposed that light emits energy in small packets (quanta)
Quantum Mechanical Model
the current model of the atom
line-emission spectrum
a diagram that indicates the energy emitted of the electron precisely, and its probable location
