3rd lecture - radial distribution

Question 1

what does the schrodinger equationn describe

Answer 1

electrons

Question 2

what does the radial wavefunction depend on

Answer 2

distance from nucleus
independent of direction

Question 3

what does the angular wavefunction depend on

Answer 3

direction
independent of distance

Question 4

where is the radial wavefunction largest at

Answer 4

largest at the nucleus

Question 5

why is the radial wavefunction asymptotic

Answer 5

it never reaches 0

Question 6

when n and l and ml are 0, how many radial wavefunction graphs are there

Answer 6

1

Question 7

when n=2 and so l has 2 possible values, how many radial wavefunction graphs are there

Answer 7

2

Question 8

when n=3 and so l has 3 possible values, how many possible radial wavefunction graphs are there

Answer 8

3

Question 9

what is it when the line on the radial wavefunction graph goes below 0 on the x axis

Answer 9

the phase of the wavefunction !!!!!!

Question 10

radial distribution function

Answer 10

how many possible locations an electron can occupy at a given distance

Question 11

radial distribution function equation

Answer 11

rdf =
probability of an e- being at distance r x. number of locations at distance r

Question 12

what is the number of locations at distance r

Answer 12

the surface area of a sphere
where radius is 4nr^2

n=pi

Question 13

as quantum number n increases, what happens to max probability density

Answer 13

increases
n determines size and energy

Question 14

as quantum number l increases, what happens to the max probability density

Answer 14

nothing
l is the shape

Question 15

node

Answer 15

area where the probability of finding an electron is 0.

Question 16

radial node

Answer 16

distances from the nucleus where the probability of finding an e- is 0

passing the y axis.
