Chapter 1: Atomic Structure

Question 1

Plank’s Relation (frequency)

Answer 1

E = h f

E = energy
h = Planck’s constant
f = frequency

Question 2

Avogadro’s Number

Answer 2

Na= 6.02 x 10^23

Question 3

Speed of light

Answer 3

c = 3 x 10^8 m/s

Question 4

Plank’s Constant

Answer 4

h = 6.626 x 10^-34 J.s

Question 5

Angular momentum of an electron (Bohr model)

Answer 5

L = n h / 2π

n = the principal quantum number
h = planks constant

Question 6

Energy of an Electron (Bohr Model)

Answer 6

E = - Rh c / n^2

Rh = Rydberg cosntant (1.097 x 10^7 m^-1)
c = speed of light
n = quantum level

Question 7

Plank’s Relation ( wavelength)

Answer 7

E = h c / λ

λ = wavelength
c = speed of light
h = planks constant

Question 8

Maximum number of electrons within a shell

Answer 8

2n^2

Question 9

Maximum number of electrons within a subshell

Answer 9

4ℓ + 2

Question 10

Energy of electron transition (Bohr Model)

Answer 10

E = Rh [1/ni^2 - 1/ nf^2]

Rh = Rydberg cosntant (1.097 x 10^7 m^-1)
n = quantum level
