chem quantum mechanical quiz

Louis de broglie

proposed that electron's should be considered as waves

James Maxwell

demonstrated that electric and magnetic fields travel through space as waves at the speed of light.

Max Planck

proposed that light emits energy in small packets called quanta

Werner Heisenberg

determined that it is impossible to know an electron's position and energy simultaneously

Albert Einstein

stated that while light has wavelike properties, it is also a stream of particles called photons. (dual wave-particle nature)

Erwin Schrödinger

developed equations that solved for the energy of the electron precisely, and its probable location

Niels Bohr

developed a model of the atom in which the electron can only circle the a nucleus in allowed paths, called orbits, and there is nothing in between.

Photoelectric Effect

The memos on of electrons form a metal when light shines on the metal

Excited state

Atoms absorb energy- electrons move from a low energy level to a higher

Ground state

Lowest energy state

Quanta

Little packets of energy

Orbitals

Electrons exist in this certain region (around the nucleus)
