Electrons (Bohr’s Incorrect Model) Flashcards
The first scientist to come up with a plan on the structure of the atom
Niels Bohr
Bohr wanted to know where
Electrons were located in the atom
Bohr proposed idea that electrons zoom around atom like
Planets zoomed around sun
Electrons _
Orbit
Bohr called the orbits of electrons _
Energy levels
An energy level is the possible location around a nucleus where
An electron may be found
Each energy level has a specific (2)
Size
Energy
The energy of each energy level is related to its
Size
The smaller the level, the _
Lower the energy
Each energy level is _ from the nucleus
A fixed distance
Energy levels are numbered starting from _
Nucleus
Bohr thought that the only way electrons could gain or lose energy was
To move from one energy level to another
When electron moves from higher energy level (farther away from nucleus) to lower energy level _
It releases energy, emitting a photon in the process.
Bohr’s model was later discovered to be
Incorrect
