Arrangement of elect

Arrangement of electrons in the atom

Energy level is defined as the fixed energy value that an electron in an atom may have.
E=hf definite amount of energy emmited from an atom is equal to definite frequency.
an orbital is a region in space within which there is a high probability of finding an electron.
Heisenberg's principle states that it is impossible to measure at the same time both the velocity and the position of an electron.
