(break it apart)
Electron shells - answer ✔✔-An atom has defined energy levels, each at a different distance from the
nucleus called
The atomic number - answer ✔✔-______ of an atom refers to the number of protons it contains in its
nucleus

molecule - answer ✔✔-Two or more atoms bonded together form a
chemical compounds - answer ✔✔-combinations of elements bonded together.
isotope - answer ✔✔-refers to elements whose atoms have the same number of protons but a different
number of neutrons.
, isotone - answer ✔✔-refers to elements whose atoms have the same number of neutrons but a
different number of protons.

electrons - answer ✔✔-Atoms in each group have the same number of ______ in the outermost shell
Covalent bonding - answer ✔✔-is based on two atoms sharing electrons that then orbit both nuclei
Ionic bonding - answer ✔✔-is based on the attraction of opposing charges.
electromagnetic radiation - answer ✔✔-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
atom - answer ✔✔-Electromagnetic radiation is a form of energy that originates from the
The amplitude - answer ✔✔-refers to the maximum height of a wave.
Frequency - answer ✔✔-refers to the number of waves that pass a given point per second
inverse square law - answer ✔✔-used to calculate the change in the intensity (quantity) of radiation
reaching the image receptor with changes in distance.
Radioactivity - answer ✔✔-is a general term for the process by which an atom with excess energy in its
nucleus emits particles and energy to regain stability.
radioactive decay. - answer ✔✔-This process of a radioactive element giving off excess energy and
particles to regain stability is known as
radioactive. - answer ✔✔-Elements that are composed of atoms with unstable nuclei are said to be
