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.
The joining of light nuclei into a heavier nucleus
Fusion
Length of Time (T)
