Answer 1

30kda

Question 2

what is the bohr model?

Answer 2

bdige between the planetry model and full quantum model, suggests electrons as waves

Question 3

what is the wavelenth of an electron proportional to?

Answer 3

inversely proportional to their momentum

Question 4

what is the de brogue equation?

Answer 4

shows that wavelength is inversely proportiona lt ot momentum
lambda= h/p
h= plancts constant
p = mass x velocity

Answer 7

represented by s no. (curvy bottom) L

Question 8

what does the principle quantum number tell you?

Answer 8

how large the orbital is

how far the nucleus is from the outer most antinode

Question 9

what does the asmithual quantum number tell you?

Answer 9

doesnt exist for 1d string

Question 10

what is the probability density?

Answer 10

how likely you are to find electrons from nucleus

in 1s probability decreases exponentially with distance from nucleus
