Nuclear Chemistry Particles
the study of the changes that occur in the nucleus of atoms
What is Nuclear chemistry
When the atomic nucleus of one element is changed into the nucleus of a different element, the reaction is called a
what is a transmutation
The time it takes for half a radioisotope sample to decay
what is a half life
Carbon-14/12 is used for
what is fossil dating
The nucleus is the center of an atom contains
What are protons and neutrons
Radioisotope naturally decays by emitting (releasing) a specific particle
Natural transmutation
X has a half life of 1 day what fraction is left after 1 day
what is 1/2
Cobalt-60 is used for
what is cancer treatment
The ratio of neutrons to protons determines
what is stability
Purposeful bombardment (hitting) a nucleus with a high-speed particle to change it into a different atom
what is Artificial transmutation
X has a half life of 1 year what fraction is left after 2 years
what is 1/4
Carbon-14 alone can be used for
what are tracer for chemical reactions
When atoms aren’t stable, they emit
what are small particles
One large nucleus breaks up into smaller nuclei
Fission
X has a half life of 1 day what fraction is left after 1 week
what is 1/128th
Technetium-99 can be used for
what is a cancer tumor diagnosis
Less stable isotopes are called
what are radioactive isotopes.
