answers | Updated NEW 2026
The earliest atomic theory based on an arrangement similar to the solar system is a ributed to
Rutherford.
The three fundamental par cles of the atom are the
neutron, electron, and proton.
The atomic nucleus contains
protons and neutrons.
The component of the nucleus that has a posi ve charge and mass is the
proton.
The electron shell closest to the nucleus is le ered
"K".
Which of the following is not part of the electromagne c spectrum?
Sound
Which of the following electromagne c radia ons have the lowest energy level?
Radio waves
As the wave's frequency increases, the wavelength
decreases.
Frequency is typically measured in
hertz.
The process of removing an electron from an atom is
ioniza on.
X-rays are produced
using fast-moving electrons.
, Which of the following helps to keep the x-ray tube cool on the inside of the protec ve housing?
Cooling fans and an oil bath
In terms of the x-ray tube, envelope is another name for the
glass or metal enclosure.
The posi ve end of the x-ray tube is the
anode.
The nega ve end of the x-ray tube is the
cathode.
The area of the envelope where x-rays should exit the tube is the
target window.
The anode serves as a(n)
target for the electron interac on to produce x-ray, electrical conductor, heat conductor.
The two types of anode designs are sta onary and
rota ng.
Tungsten is used to coat the anode disc because it
has a high atomic number.
With a rota ng anode, the focal spot becomes a focal
track.
X-rays are produced by
characteris c and bremsstrahlung interac ons.
When filament electrons enter the anode target, they interact with
outer shell electrons of tungsten atoms.
When a filament electron knocks out a K shell electron from the tungsten atom, it leads to
a characteris c x-ray photon.
The energy of the characteris c x-ray photon depends on
