Basic Physics for Radiography Flashcards
What are the three basic forms of matter:
Solid,LIquid,Gas
The Quantity of matter that makes up any physical object
Mass
The Law of Conservation
Matter can neither be created nor destroyed but can change its’ form.
Energy can neither be created nor destroyed but it can change it’s form.
All matter is composed of “building blocks” called
Atoms
The fundamental particles that compose atoms are:
Neutrons ,Protons and Electrons
What forms the Nucleus:
Neutrons and Protons
Electrons circle the nucleus in orbits called:
Shells
The closest shell to the nucleus and most important :
K-Shell
A substance made up of only one type of atom:
Element
Three most common elements we may be familiar with are:
Calcium(Ca),Iodine(I) and lead (Pb)
Three most common elements we may be familiar with are:
Calcium(Ca),Iodine(I) and lead (Pb)
The greater the Atomic Number,
The greater the Mass and Density
The mass number of the element is the combined total of:
Protons and Neutrons in a Nucleus
The most important element used in production of X-rays and element inside of X-ray tube where X-rays are created:
Tungsten
Two or more atoms may combine chemically to form:
Molecules
A substance that consists of only one type of molecule is called:
Chemical Compound
When a neutral atom gains or loses an electron and is said to be the process:
Ion,Ionization
