Quantum Numbers
The quantum number that determines the energy level or shell of an electron.
What is the principal quantum number (n)?
The orbital shape that corresponds to l = 0
What is an s orbital?
The electron configuration of hydrogen
What is 1s1?
The principle that states that an orbital can hold a maximum of two electrons with opposite spins
What is the Pauli Exclusion Principle?
The reason different elements emit different colors in fireworks
What is because electrons move between energy levels and give off different colors of light?
The quantum number that determines the shape of the orbital.
What is the angular momentum quantum number (l)?
The orbital shape that corresponds to l = 1
What is a p orbital?
The number of electrons that can occupy the 2p subshell
What are 6 electrons
The principle that states electrons fill orbitals of lowest energy first
What is the Aufbau Principle?
Common electronic devices through which electrons move
What are computers and phones?
The quantum number that determines the orientation of an orbital in space.
What is the magnetic quantum number (ml)?
The number of orbitals that are found in a p sub-shell
What are 3 orbitals?
The electron configuration for Nitrogen
What is 1s22s22p3?
The principle that states that electrons occupy available orbitals singly before pairing up
What is the Hund's Rule?
The reason metals conduct electricity well
What is because their electrons can move freely between orbitals?
The quantum number that determines the spin of an electron.
What is the spin quantum number (ms)?
The reason an s subshell can hold fewer elctons than a p subshell
What is because an s subshell contains only 1 orbital, while a p subshell contains 3 orbitals?
The name and number of valence electrons of an atom with the electron configuration 1s22s22p63s23p4
What is a neutral Sulfur atom, and 6 valence electrons?
The reason electrons fill separate p orbitals before pairing up
What is because it minimizes electron-electron repulsion?
LED lights produce light when electrons move between different energy levels in atoms. When they drop to a lower energy level, this happens
What is light is emitted?
For n=4, the possible values of l are
What are 0,1,2 and 3?
The name of the subshell that contains five orbitals and the number of electrons it can hold
What is a d subshell, and it can hold 10 electrons?
The name and number of valence electrons of an atom with the electron configuration 1s22s22p63s23p1
What is a neutral aluminum atom, and 3 valence electrons?
If three electrons occupied the same orbital, the following principle would be violated
What is the Pauli Exclusion Principle?
The reason scientists can't know the exact location of an electron at all times
What is because of the Heisenberg Uncertainty Principle?
