9/27 notes

Question 1

sketch a graph of the probability distribution versus distance for 1s orbital

Answer 1

ok

Question 2

how does the average distance compare to the most probable distance

Question 3

what indicates the size of an orbital

Question 4

what is a node

Question 5

why is the 2s called the radial node

Question 6

what is a planar/angualr node

Question 7

what shape are s orbitals and what are their directinoalilty

Answer 7

spherical and have no directionalitu

Question 8

probabilty of finding electron in 1s orbital

Answer 8

90% probable but it is not uniform

Question 9

r is

Answer 9

distance from nucleus

Question 10

node

Answer 10

zero probabilty of finding electron

Question 11

shape of p orbital and their orientation

Answer 11

dumbell shape and three orientations

Question 12

planar node

Answer 12

zero probability of finding node on plane

Question 13

d orbitals shape and orientation

Answer 13

clover and five

Question 14

rules for counting nodes
-Total:
-number of planar nodes
-number of radial=

Answer 14

total: n-1

always = to L quantum number

(n-1)-L

Question 15

draw orbitals p and d on axes and draw graph of each orbital

Answer 15
