Equations

Question 1

State equation relating frequency wavelength to the velocity of light

Answer 1

wavelenght*frequency = speed of light

Question 2

Equation relating energy of a photon with frequency?

Answer 2

E = hv

Question 3

State the de Brogile Relationship

What does the relationship show

Answer 3

Wavelength = h/p

p = momentum = mass * velocity

How electrons can behave like particles or waves

Question 4

State heisenbergs uncertainty principle

Answer 4

Dx•dpx morethanoreqto h/4pi

Question 5

State shrodingers equation

Answer 5

Hpsi = Epsi

Question 6

Aufabau principle

Answer 6

To move from one element to next, add one proton and x nuetrons to the nucleus and one electron into the orbital of lowest energy available.

Question 7

Pauli Exclusion Principle

Answer 7

No 2 electrons can have identical values for all 4 quantum numbers

Question 8

Hund’s rule

Answer 8

The most stable ELECTRONIC state is one with the most parralel spins

Question 9

Meaning of symmetry operation i

Answer 9

i is the symmetry operation of inversion

Question 10

State and explain the nernst equation

Answer 10

dG(red) = -nFE(red)

To plot we use dG/F

Question 11

Slaters Rules

Answer 11

(1s2)(2s2, 2p6) (3s2, 3p6) (3d10) (4s2, 4p6)

Question 12

Spin only formula and its units

Orbital contribution, yes or no?

Answer 12

Uso = root(n(n+2)) Ub

Where Ub is the units

Yes if T state and no if A state (1 way) or E state (2 way)
