An electron in an atom can move from one energy level to another when the atom gains or loses energy
Scientists use the electron cloud model to discribe the possible locations of electrons around the nucleus
An electron cloud is a good approximation of how electrons behave in their orbitals
The most stable electrion configuration is the one in which the electrons are in orbitals with the lowest possible energies.
It represents the electrons that are too fast to know where they are at one point in time.
The 2 electrons on the first orbital have an energy level of 1 while the 3 electrons on the 2nd orbital have an energy level of 2
Incomplete - the Bohr Model shows that instead of flying around the nucleus randomly, the atoms actually flew around it in fixed circles.
The location of the electrons are unexpected and can never be known as they are too fast to know with 100% certainty. We need to use probability to predict where it is.
