What are isotopes?
Elements with the same number of protons and different number of neutrons.
protons + neutrons
A substance has a half-life of 24 days, started with 100 g how much is left after 48 days?
What is 25 grams
What is fusion?
The fusing of 2 smaller nuclei into a heavier nuclei.
What is the name of an isotope with a mass number of 39 and an atomic number of 15?
Phosphorus-39
Compare and contrast fission vs. 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.
What type of reaction solely produces pure energy with no change to mass number or atomic number?
gamma
A substance is 24,110 years old. How much of 100 g remains after 96,400 years?
What is 6.25 grams
Which process is known for using uraniuim-235 and plutonium-239 as a fuel source?
What is Fission
How many protons, neutrons, and electrons does the following isotope have?
Uranium-235
Fusion uses what is the isotope name of 1 of fusion's fuel sources?
hydrogen-2 or hydrogen-3
What type of radiation can only travel 2-3 meters?
beta
A substance has a half life of 15 years, how much of 15.0 g is left after 60 years.
What is 0.94 g
Which process results in the production of an immense amount of energy compared to the other?
What is Fusion
What is the name of an isotope with a mass number of 12 and a atomic number of 6.
Carbon-12
Write a correct chemical equation for alpha decay using any element (all parts should be in isotope notation)
A substanc has a half life of 16 days. How many days are required for the substance to decay to 1/8 of its original amound?
What is 48 days
Which process is produces less waste and is considered "green energy"?
What is fusion
Describe what "isotope notation" means.
Top number=mass number; bottom number=atomic number; to the right is a symbol for the element.
