Nuclear Decay Study Review with Complete Solutions
protons and neutrons - -located in the nucleus
strong nuclear force - -the attractive force that binds
protons and neutrons together in the nucleus
82 protons - -elements with more than this number
of protons are radioactive
92 protons - -Elements with more than this number
of protons are man-made
Radioactivity - -The process in which some
substances spontaneously emit radiation
Isotope - -Atoms of the same element that have
different numbers of neutrons
Atomic number - -the number of protons in the
nucleus of an atom
atomic mass - -Number of protons and neutrons
alpha, beta, gamma - -three types of radiation
alpha particle - -a type of nuclear radiation
consisting of two protons and two neutrons
A piece of paper - -The material that can be used to
stop an alpha particle
Inside the body - -Place that alpha particles can
cause damage
beta particle - -a high-speed electron with a 1-
charge that is emitted during radioactive decay
Neutron - -The proton and electron in a beta decay
come from this particle
3 mm of aluminum - -Material needed to stop a beta
particle
gamma rays - -electromagnetic radiation arising
from the radioactive decay of atomic nuclei.
7 cm of lead - -Material needed to stop gamma rays
Transmutation - -the conversion of one element to
an atom of another element
Beta decay - -The type of decay shown
Alpha decay - -Type of decay shown
alpha particle - -type of nuclear decay particle
shown
