Atomic Orbitals. The Bohr Model ( Niels Bohr). In 1913, Niels Bohr came up with a new model (Bohr was a student of Rutherford).
In 1913, Niels Bohr came up with a new model (Bohr was a student of Rutherford)
He noticed that light given out when atoms were heated always had specific amounts of energy, so Niels Bohr proposed a model that electrons in an atom must be orbiting the nucleus and can reside only in fixed energy levels
The quantum mechanical model does not describe the exact path an electron takes around the nucleus, but determines the probability of finding an electron in a certain area
A region of space where electrons are likely to be located.
Each energy level can be made up of sublevels, which is made of different orbitals
Draw an s orbital.
Now draw a 2s orbital. How are they different?
Draw three p orbitals.
Now, draw all three p orbitals on an x-y-z axis
