Orbital Theory, continued
Electron Arrangement
100
The probable location of an electron with in an atom
What is an orbital?
100
States that Orbitals can hold a maximum of 2 electrons.
What is Pauli's exclusion principle OR Pauli's principle?
100
This one of the many models of atoms that describes electrons as moving around the nucleus like "bees around a hive"
What is Bohr's model?
100
The following electron configuration corresponds to this element. 1s2 2s2 2p4
What is O or oxygen?
200
The sublevel/orbital with the lowest energy.
What is 1s?
200
This states that every orbital in a sublevel gets one electron before any other orbital gets two electrons.
What is Hund's Rule?
200
This model of the atom is described as looking like fan blades due to the electron cloud. (2 words)
What is the quantum mechanical model?
200
The following electron configuration refers to this element. 1s2 2s2 2p6 3s2 3p5
What is chlorine (Cl)?
300
The maximum number of electrons that can be in the 3d sublevel.
What is 10?
300
This describes the filling order for sublevels in an atom, and is based on increasing energy (2 words)
What is the aufbau principle?
300
The amount of energy needed for an electron to move from one energy level to another.
What is quantum?
300
This is the electron configuration for potassium (K).
What is 1s2 2s2 2p6 3s2 3p6 4s1 ?
400
These are the orbitals in the n = 4 energy level.
What are s,p,d,f?
400
Says that electrons in an orbital must have opposite spins.
What is Pauli's principle?
400
This refers to the energy level of an electron as indicated by whole numbers 1,2,3, etc.
What is the principal quantum number?
400
This is the electron configuration for bromine.

500
The number of d orbitals in a sublevel
What is 5?
500
This is the sublevel that comes next in order of energy..... 1s 2s 2p 3s 3p ______
What is 4s?
500
This is the way electrons are arranged in various orbitals around the nuclei of atoms.
What are electron configurations?
500
This is the electron configuration for barium (Ba).
