Smallest unit of measurement, basic building block of matter. - ANSWERS
atom
is also a measure of the amount of energy necessary to split an atom (break it
apart) - ANSWERS Binding energy
An atom has defined energy levels, each at a different distance from the nucleus
called - ANSWERS Electron shells
______ of an atom refers to the number of protons it contains in its nucleus -
ANSWERS The atomic number
is the number of protons and neutrons an atom has in its nucleus - ANSWERS
The atomic mass number
_______ are the simplest forms of substances that compose matter -
ANSWERS Elements
Two or more atoms bonded together form a - ANSWERS molecule
combinations of elements bonded together. - ANSWERS chemical compounds
,refers to elements whose atoms have the same number of protons but a different
number of neutrons. - ANSWERS isotope
refers to elements whose atoms have the same number of neutrons but a
different number of protons. - ANSWERS isotone
Atoms in each period have the same number of - ANSWERS electron shells
Atoms in each group have the same number of ______ in the outermost shell -
ANSWERS electrons
is based on two atoms sharing electrons that then orbit both nuclei - ANSWERS
Covalent bonding
is based on the attraction of opposing charges. - ANSWERS Ionic bonding
is very similar in that it has no mass, carries energy in waves as electric and
magnetic disturbances in space, and travels at the speed of light - ANSWERS
electromagnetic radiation
Electromagnetic radiation is a form of energy that originates from the -
ANSWERS atom
refers to the maximum height of a wave. - ANSWERS The amplitude
, refers to the number of waves that pass a given point per second - ANSWERS
Frequency
used to calculate the change in the intensity (quantity) of radiation reaching the
image receptor with changes in distance. - ANSWERS inverse square law
is a general term for the process by which an atom with excess energy in its
nucleus emits particles and energy to regain stability. - ANSWERS Radioactivity
This process of a radioactive element giving off excess energy and particles to
regain stability is known as - ANSWERS radioactive decay.
Elements that are composed of atoms with unstable nuclei are said to be -
ANSWERS radioactive.
current heats the filament to a point of incandescence (white hot), and electrons
are literally boiled off of the filament by thermionic emission. The focusing cup
forms them into a cloud called - ANSWERS space charge
higher energy level - ANSWERS excitation
infrared radiation - ANSWERS heat
This process of outer-shell electrons filling inner-shell vacancies continues down
the line, creating a cascading effect called a - ANSWERS characteristic cascade
