Exam 3 Chapter 6

Question 1

wavelength

Answer 1

symbol: lambda

distance between identical points on adjacent waves
shorter wavelength = more energy
longer wavelength = less energy

Question 2

Visible Light spectrum

Answer 2

350-800nm

Question 3

Frequency (nu)

Answer 3

number of waves that pass a point per time (units time ^-1)
directly proportional to energy

Question 4

Speed of light (c)

Answer 4

c = 3.00*10^8 m/sec

Question 5

Energy

Answer 5

(h*nu)/lamda

(Planck’s Constant * frequency)/wavelength

Question 6

Planck’s Constant

Answer 6

6.6310^-34 Jsec

Question 7

Rydberg Equation

Answer 7

-used to calculate energy transitions of electrons

R(1/n1^2 - 1/n2^2)

Question 8

de Broglie Equation

Answer 8

the wavelength of a moving particle

wavelength = Planck’s constant/ (mass*velocity)

Question 9

‘Orbit’ of a Bohr model is a ______ in quantum theory

Answer 9

probability function

Question 10

n

Answer 10

n: principal quantum number

defines the location of the energy level (shell number)

Question 11

l

Answer 11

l: angular momentum quantum number

between 0 and n-1
subshell, or shape of the orbital

Question 12

ml

Answer 12

ml: magnetic quantum number

between -l and l
orientation of the orbital

Question 13

ms

Answer 13

ms: spin quantum number

1/2 or -1/2
direction of the electron’s spin
