What property of electrons were introduced?
Wave properties
A region of probable location of electrons
How many electrons have the same 4 quantum numbers in any given element?
None
Who discovered the electron?
Thompson
Orbital circumference has to fit what waves?
Orbital circumference has to fit WHOLE waves
What is subshell number 3 notation letter?
What are the dimensions of an orbital?
3-D
Who introduced the idea of matter having wave like properties?
De Broglie
What were Bohr's orbits replaced by?
Orbitals
What are the allowed values of Ms
-1/2 or +1/2
How many electrons are allowed per orbital?
2
Is the electron configuration [Xe] valid? Why or why not?
The electron configuration [Xe] is not valid as in condensed electron configuration you are required to put the noble gas before, this is the noble gas of, which is not allowed
Who preformed the gold foil experiment and what did it prove?
Rutherford did the experiment and it proved that the atom is mainly empty space with a nucleus
What is the Aufbau principle?
Each electron is added into the subshell with the lowest energy orbital available
What does magnetic quantum number represent?
The orientation of the orbital
What is the shape of an s orbital?
Sphere
What is the order of filling the orbitals up to 5s?
1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s
Which scientist had the limitation on their theory of only being able to explain single electron atoms?
Bohr
What is Heisenberg's uncertainty principle?
It is impossible to predict with certainty the position and momentum of an electron
What are the quantum numbers for the 23rd electron in copper
n=3 L=d ML=0 MS=+1/2
What is Hund's rule?
Each orbital subshell gets a single electron first before the second electron is paired. All electrons are up when single
What are the 3 different ways electron configuration can be written?
1. Energy diagram
2. Complete electron configuration
3. Condensed electron configuration
