1s22s22p63s1
What is Sodium?
This period 4 transition metal has an expected configuration ending in 4s23d4, but its actual configuration ends in 4s13d5.
What is Chromium?
The spin quantum number describes this.
What is the spin of an electron?
The principal quantum number, n, corresponds to this fundamental property of an atomic orbital.
What is its size?
These elements have completely full s and p subshells.
What are the noble gases?
1s22s22p4
What is Oxygen?
This element's actual configuration is [Ar]4s13d10 in order to achieve a fully filled, highly stable d-subshell.
What is Copper?
When waves of equal amplitude from two sources are in phase when they interact.
What is Constructive Interference?
If an electron is located in a p-orbital, it must have this specific value for its angular momentum quantum number (l).
What is 1?
This takes the shape of a dumbbell.
What is a p-orbital?
1s22s22p63s23p64s23d6
What is Iron?
Unlike its group siblings Chromium and Molybdenum, this heavy metal actually follows the rules, ending with a standard 6s25d4.
What is Tungsten?
This principle states that no two electrons in the same atom can have the exact same set of all four quantum numbers.
What is the Pauli exclusion principle?
This is the maximum number of electrons that can exist in an atom with the quantum numbers n=4 and l=2.
What is 10?
This orbital has 7 configurations.
What is the F-orbital?
[Kr]4d105s25p6
What is Xenon?
Period 5 is notoriously messy. This element shifts an s-electron to become 1s22s22p63s23p63d104s24p64d45s1, proving that exceptions happen even without achieving a perfect half-filled d-subshell.
What is Niobium?
The systematic pattern for filling up the electron configuration, from low energy to high energy, for an element.
What is the Aufbau Principle?
A valid set of four quantum numbers (n, l, ml, ms) for the very first electron added to a Lithium atom.
What is n=1, l=0, ml=0, ms=+1/2?
This phenomenon explains how a 2s electron can spend a tiny fraction of its time very close to the nucleus, making it lower in energy than a 2p electron.
What is penetration?
1s22s22p63s23p64s23d104p65s24d105p66s24f145d7
What is Iridium?
Palladium is entirely unique among the transition metals because it promotes two s-electrons to the d-orbital. This is its shorthand configuration.
What is [Kr]4d10?
This rule dictates that every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied.
What is Hund's Rule?
If an electron has quantum numbers n=3 and l=1, these are the only possible values for its magnetic quantum number (ml).
What are -1, 0, and +1?
