Electron Configuration
The technique of writing electron configurations with arrows is known as
What is orbital notation or orbital diagrams

What is a quantum
The spin quantum number says that the number of spins an electron can have is
What is 2
The rule that says two electrons in the same orbital in the same sublevel can not have the same spin state.
What is Pauli's exclusion principle
The rule that states electrons will fill separate orbitals in the same energy level first before pairing up in the same orbital
What is Hund's rule
The number of electrons that can fill the sublevel 4f
What is 14
When an electron moves from a higher energy level to a lower energy level, energy is _____________.
What is released
Which of the following locations of an electron is not possible: 3s, 4f, 3d, 1p, 2p, 1s
What is 1p
The rule that states electrons will fill the lowest energy levels first
What is Aufbau's principle
Write the electron configuration (not orbital notation or noble gas notation) for Germanium (Atomic Number 32)
What is 1s(2), 2s(2), 2p(6), 3s(2), 3p (6), 4s(2), 3d(10), 4p (2)
The 4 quantum numbers and what they mean
What is
1. principle quantum number
2. Sublevels found in each energy level
3. The number of orbitals found in each sublevel
4. The Spin
The model of the atom that predicts the likelihood or probability of finding an electron in a certain location known as an orbital or electron cloud
What is the quantum mechanical model
The number of electrons needed to completely fill the 4th energy level
What is 32
Give the noble gas notation for Potassium
What is [Ar] 4s(1)
Using an orbital diagram show how an example that would violate Hund's rule of the orbital diagram of Nitrogen (Atomic Number 7)
What is diagram would have two paired electrons instead of each in its own orbital in the 2p sublevel
Give the number of orbitals that can be found in the main energy level of 3.
What is 9 (s=1, p=3, d=5)
What was the behaviour of electrons in experiments that Rutherford's model could not explain
What is an atomic emission spectrum that each element emits a certain colour light when electrons release a certain number of photons moving from an excited state to a ground state.
The sublevels that are known to exist in the 6th energy level
What is s, p, d, f
Show an orbital diagram that would violate the Pauli exclusion principle for Mg (Atomic Number 12)
What is 2 arrows in the same orbital that are both up or both down
Name the element with the following electron configuration by using the periodic table method: [Xe] 4f (14), 5d (10),6s(2),6p (3)
What is Bi (bismuth)
The number of electrons in the outermost energy level of an oxygen atom
What is 6
The difference between Bohr's model of the atom and the quantum mechanical model of the atom
What is Bohr: electrons are found in a circular orbit in a fixed location, QMM: the exact location of an electron can not be found but instead the electron cloud can show the orbital where it is most likely to be found
