Quantum Mechanics

Energy can be transferred as (3)

Work, heat and electromagnetic radiation

blackbody radiation

energy emitted by an object when heated

Electromagnetic spectrum from low energy to high energy (high wave length to low)

RMIVUXG

blackbody raidation

electromagnetic energy emitted when an object absorbs energy

What word did Einstein coin

photon

how fast do electromagnetic waves travel

speed of light

what is wave length

distance between two neighboring peaks

Armstrong to meter

1 arm strong=10^-10 m

Frequency

the number of cycles that pass through a point per second

What is frequency measured in

Hz or 1/second

Light speed formula

c=(λ)(ν)

What determines light

wave length

What is the visible light spectrum made up of

roygbiv

What does high frequency correlate with

high energy

What does low frequency correlate with

low energy

Max planck

energy can be gained or lost only in integral multiples called multiples (SO COOL)

What is a photon

a packet of electromagnetic radiation

Energy formula with planck

E=hv

photoeletric effect

light behaves has both a wave and a particle, it has the power to knock electrons out a place, the energy needed to do so is called threshold frequency

What determines energy of a photon

color/frequency

What does excess energy in threshold frequency do

becomes excess KE of in electrons

What gives light it’s wave properties

electromagnetic radiation

What gives light it’s particle property

it’s photoelectric effect

absorption spectrum

the color needed to move electron to an energy level/ what colors has been absorbed

emission spectrum

the energy released to go back to ground state/what colors has been emitted

Rydberg equation watch out

Can only be used for hydrogen atoms

n value meaning

the larger the n value the larger the orbital

n—>n1

UV and lynman

n543—>n2

visible and bomber

n54—>n3

infrared and passionate

ionization energy

energy needed to remove one electron from a gaseous electron

Particles duality

all particles have wave/particle duality

de Brogile Wavelength

λ= (h)/(mv) h=planck’s constant m=mass(kg) and v=velocity

Heisenberg uncertainty

you cannot know velocity and position at the same time

What did Schrodinger do

made a wave function to find probability of an electron

principle number n

size of orbital and energy level, larger n, the farther away from the nucleus it is

angular momentum quantum ℓ

shape of orbital, 0=s,1=p,2=d,3=f,4=g,5=h (n-1)

magnetic quantum number mℓ

orientation -ℓ,0,ℓ

number of node equation

n-1

What is a shell

collection of orbital with the same principle number

what is a subshell

a collection of orbital with the same n and ℓ

what makes one orbital

n,ℓ, and mℓ

The higher the energy drop

the higher the energy release meaning small wave length
