How were X-rays discovered
Dr. wilhem connor roetgen used a chemical painted on a piece of cardboard and a cathode tube to look for rays
Who created X-rays
Dr. Wilhem Connor Roetgen
what charge is a Cathode
Negative
what charge is an Anode
Positive
What are the fundamental quantities for the unit of measure (3)
Mass, time, length
What are the derived quantities (5)
velocity, work, power, acceleration, force, momentum
what are the special quantities (4)
dose, dose equivalent, exposure, radioactivity
Leucippus
associated with the earliest atomic history
democritus of abdera
student of leucippus that hypothesized that all things were made of atoms were indestructible
john dalton
matter is made up of all atoms that are indestructible and atoms have different weights and components
dmitri mendeleev
organized elements into periodic tables
joseph john
discovered electrons by cathode ray tubes and created “plum pudding model”
What does the atom contain
protons and neuron
What is needed to break an atom
depends on how many protons to an atom and if its closer to the nucleus then harder to break apart
What is characteristic
radiation coming in and hits electron and fills the hole
what is bremsstrahlung
radiation doesnt come in and doesnt touch anything
how many electrons can L hold
8
how many electrons can M hold
18
what are the electron shells lettered from
outwards from K
how many electrons can K hold
2
how many electrons can N hold
32
what are isotopes
same # of protons but different neutrons
what are isotones
same number of neutrons but different protons
what are isobars
same protons and neutrons mass number but different protons (atomic number)
