Bohr's Theory of the Hydrogen Atom, OpenStax Flashcards
Who is Niels Bohr?
Niels Bohr is known for publishing his theory about the simplest atom (hydrogen) based on the planetary model of the atom.
Bohr used the planetary model of the atom to…
Explain the atomic spectrum and size of the hydrogen atom.
Electrons in atoms can only exist…
In discrete orbits.
The orbits of electrons in atoms are…
Quantized.
Each orbit has…
A different energy.
Electrons can move to a higher orbit by…
Absorbing energy.
Electrons can drop to a lower orbit by…
Emitting energy.
If the orbits are quantized, the amount of energy absorbed or emitted is…
Also quantized, which produces discrete spectra.
What are the primary methods of transferring energy into and out of atoms?
Photon absorption and emission.
The centripetal force causing the electron to follow a circular path is supplied by…
The Coulomb force.
If a nucleus has Z protons and only one electron, that atom is called…
A hydrogen like atom.
Bohr’s model is what we call..
Semiclassical.
Semiclassical means…
That the orbits are quantized (nonclassical) but are assumed to be simple circular paths (classical).
