Neils Bohr's atomic theory is similar to the concept of the
solar system
circles with dots
spinning wheel
None of the above
Bohr's model answered the problem in Rutherford's model that
electrons are not spinning at all
electrons are spaced
electrons are free to move around the nucleus
spinning electrons will eventually lose energy and collides to the nucleus
When an electron absorbs enough energy, it jumps up to a higher level. This is called
absorption state
excitation state
emission state
relaxation state
Soon after the electron absorbs energy, this energy is released in a form of light or photon, this is the
absorption state
excitation state
emission state
relaxation state
According to Bohr, the energy absorbed by an electron upon excitation comes in a fixed amount called
exact energy
fixed energy
quantized energy
None of the above
Any energy absorbed by an electron causes it to have to higher energy level
True
False
Bohr's idea about the atom is pretty good, however it has limitation. What is this limitation?
It lacks substantial evidence explaining the spectral lines of the Hydrogen atom.
His model is too simple.
His model can no longer explain the behavior of electron based on its spectral lines of atoms with more than one electron.
None of the above
The greatest contribution of Neils Bohr in the study of atom is the
energy level
orbital
spectral lines
absorption and emission of light
Because of the model's limitation, Bohr's model is rejected.
True
False
