Miscellaneous
part of the atom involved in a normal chemical reaction
What is an electron
Constructive uses of Nuclear reactions
x-rays, treat cancers, generating heat and light
What is fusion?
Two smaller nuclei combining to form a larger nucleus, releasing tremendous amounts of energy.
Part of the atom involved in a nuclear reaction.
nucleus
Why isn't fusion used in power plants?
required temperatures are too high
Who discovered radiation
Becquerel
The half life of Plutonium-239 is 24,110 years. How much of 100 g remains after 96,400 years?
What is 6.25 grams
How is nuclear fission energy harnessed in a nuclear power plant?
By boiling water to create steam which turns a turbine and generates electricity
Where does fusion occur naturally?
In the sun.
What isotope of uranium was found to be easily fissionable?
U-235
What are the reactants and products in a fission reaction?
A neutron and a fissionable isotope are reactants; more neutrons, smaller nuclei, and energy are the products
Compare and contrast fission and fusion.
both release high amounts of energy; both are nuclear reactions (involve the nucleus); fission is "splitting" a nucleus, fusion is combining 2 smaller nuclei; fission happens in nuclear power plants and atomic bombs, fusion is only observed on the sun.
