What does the slit experiment show about electrons? - ANSWER-
That they have wave like behavior.
Are electrons particles or waves? - ANSWER-Electrons are
particles that move like waves.
What does l represent? - ANSWER-l is the angular momentum
quantum number and it specifies the shape of the orbital
What does n represent? - ANSWER-n is the principle quantum
number and represents the size and energy of the orbital.
Orbitals with the same value l are what? - ANSWER-In the same
subshell.

What does m1 represent? - ANSWER-m1 is the z component of
angular momentum for a specific orbital or the orientation of the
orbital in space
What is the range of numbers for m1? - ANSWER-(-l <= m1 <= l)
What are the letters corresponding to l values? - ANSWER-
What is the range of l values? - ANSWER-(0 <= l <= n-1)
Where is electron probability the greatest? - ANSWER-R=0
What are boundary surface plots? - ANSWER-Boundary surface
plots show where an electron is most likely to be in a 2D space.
What is the relationship between n and s orbitals? - ANSWER-As
n increases s orbitals become larger and contain more nodes and
energy.
