Schrodingers cat
cat is either dead or alive..it isn’t both when its observed
cat is both dead and alive when its not being observed
What is light?
light is electromagnetic radiation moving back and forth from electric and magnetic fields
magnetic fields
region of space where magnetic particle experiences a force
electric field
-thunderstorm example
regions of space where electrical charge particle experiences a force
-you see light immediately but sound takes time to travel.
speed of light
c
3*10^8 m/s
The electromagnetic spectrum put in order from low energy to high energy -microwaves -visible light -radio -infrared(hotness you feel when you touch an object) -gamma rays (sun, stars) -UV light -xrays
radio-microwaves-infrared-visible light-UV-xray-gamma ray
a short way length has greater energy or lower energy?
lower
list these types of electromagnetic radiation in order of (i)increasing wavelength (ii) increasing energy
a) radio waves
b) microwaves
c) infared
d) Ultraviolet
(i) d,c,b,a
(ii) a,b,c,d
Pauli Exclusion Principle
no two electrons in an atom can have the same four quantum numbers
paramagnetic/diamagnetic
para-unpaired electrons
dia-paired electrons
Hunds Rule
All orbitals of equal energy must get one electron before any orbital gets two.
Coulomb’s law
- attractive forces increase between nucleus and electrons
- lower potential energy as the atoms get closer together
What are electrons?
smallest particle that makes up an atom
quantum mechanical model explain what?
the strange behavior of electrons
