chem: atom, wavelength, quantam

What are the four hydrogen jumps

3-2, 4-2, 5-2, 6-2

What does it mean when measurement has certain values

It is quantized

Light emitted or absorbed during a jump is called a what

A quantum

Louie De Boris proposes: what if electrons had wave properties meaning…

The electron can only exist in certain energy levels and there must be a whole number of wavelengths present

Hence quantum-quantized mech

Accelerating charges must emit..?

Light

A jump from one wave length to another is a…

Gain/Loss of whole number of electron wavelengths

an orbit is what type of motion ?

Accelerated

True or false? : electrons should continuously lose light and fall into the nucleus.

FALSE

• they are not actually orbiting

Democritus suggests that matter was made of tiny invisible bits called

“Atomos” (atoms)

Thompson proposes negative electrons float in a positive mist

⭐️ concept

Negative electrons surround the outside of a

Positive nucleus made of protons + neutrons

Individual atoms can emit

Energy levels are quantized and when electrons move between energy levels, atoms can emit light.

The emission spectrum tells us

The specific frequencies of light reveal the exact energy levels present within an atom's electrons

Energy levels which are infinite lead to

Atoms emitting light

Electrons only emit

1 red 1 green and 2 violets

AN ELECTRON CANT HAVE ANY ELEMENT IT WANTS, ONLY SPECIFIC ENERGY CALLED ENERGY LEVELS ELECTRONS JUMP BETWEEN LEVELS AND ABSORB SPECIFIC COLORS OF LIGHT ⭐️

Energy levels are infinite and electrons can be in between true or false?

False

• levels are infinite but electrons CANT be in between AT ALL

• They disappear and reappear

Rutherford proposes there is an atomic nucleus ⭐️

If all particles are also waves we need a

Wave length equation to predict their behavior.

Hamiltonian (H)

Represents the total amount of energy of a particle

What kind of motion is a wave?

Accelerated

• continuously emitting light and collapsing into nucleus

Cloud of electrons surround

Nucleus

Wave equation

Waves are
