Particle radiating from the nucleus of some atoms; identical to a helium nucleus
Negative particle identical to an electron but radiating from a decaying nucleus
High-intensity electromagnetic wave of energy radiating from some decaying nuclei
one or two atoms of the same element with different masses due to different numbers of neutrons
Any element can always be identified by its
number of protons, atomic number
The number of neutrons =
atomic mass - atomic number
The stability of atomic nuclei is related to the
ratio of neutrons to protons, number of protons and neutrons
An alpha particle is identical to a(n)
The particle that is identical to a high energy electron is known as
a beta particle
Alpha particles cannot penetrate deeply into solids because they
have low velocity
Beta particles cannot penetrate very far into solids because they
have no negligible mass
(T/F) Gamma rays are waves of energy that have no charge.
The Wilson cloud chamber is used to study
direction, speed, and distance of changed particles
The intensity of a radioactive sample is commonly measured using a
The new element produced along with a decay particle in a nuclear transmutation
The time required for the decay of one-half of the atoms in a sample of radioactive material
The substance that decays in a nuclear transmutation
the change of one chemical element into another by nuclear decay or radioactive bombardment
What is this?
The atomic mass.
What is this?
The atomic number.
What is this?
The symbol of the element.
How do you get the number of neutrons?
If a nuclear reaction is balanced, the reaction will
have the same mass as the parent nucleus
To find the daughter element, you must
balance out the equation
Suppose the half-life of an isotope is 10 years. After how many years will half of this isotope have decayed into its daughter element?
Suppose the half-life of an element is 10 years. How many half-lives will it take before only about 6% of the original sample remains?
The process of combining two small nuclei into one nucleus of larger mass is called
(T/F) The hydrogen bomb uses nuclear fission.
Nuclear energy is released during
fission, radioactive decay, induced splitting of atoms
Power plants produce energy by the process of nuclear
slows down neutrons
absorb emitted neutrons
mass of unstable atoms
concrete and lead enclosure
energy transfer medium
The major problems associated with the production of nuclear energy are:
hazardous solid wastes, potential reactor accidents, harm to plan and animal life
Which of the following is not a use of nuclear chemistry in industry? Thickness gauges, tracers, leak detectors, simulate plant growth
stimulate plant growth
What are the common uses of radioactive elements in health care?
soft tissue images, diagnosis of diseases, treatment of cancer
