Which are the four atomic orbitals?
(a)
Within an energy level, which orbitals are the lowest in energy?
s
f
d
p
What is the Aufbau principle?
Within an energy level, s orbitals are the lowest energy, followed by p, d and then f. F orbitals are the highest energy for that level.
The lower the principal quantum number (n) the lower the energy.
All three.
The Aufbau Principle states that electrons enter the lowest energy orbitals first.
What is the maximum numbers of electrons when n=2, l=0
(a)
Identify the rule that is being violated
Aufbau's principle
Hund's rule
Pauli Exclusion principle
Heisenberg uncertainty principle
What is incorrect about this orbital diagram?
Both arrows in the filled 2p box should be pointing the same direction
There is nothing incorrect with this diagram
In the there should only be 1 arrow in the first 2p box and one in the 2nd 2p box
All the arrows should be pointing the same direction.
