Radiation
Describe Gamma radiation using its mass and nuclear charge.
What is a mass of zero and a nuclear charge of zero?
The radioactive decay process in which the nucleus releases energy but the nuclear charge remains unchanged.
What is Gamma decay? ⁰₀γ
The splitting of a heavy nucleus into lighter nuclei, used to generate electricity in nuclear power plants."
What is fission?
Our star is this type of star according to its luminosity and temperature.
What is a Main Sequence Star?
The time it takes for a Radioactive particle to decay to ½ its original amount
What is a half-life?
This type of radiation increases the atomic number by one with each decay event.
What is Beta particle decay?
This is the balanced equation for the beta decay of
Protactinium-234
What is Uranium-234? (92 protons)
The process by which two smaller nuclei are fused into one larger nucleus.
What is nuclear fusion?
These stars tend to have very high temperatures and low luminosities.
What are White Dwarfs?
The amount of a 100g sample left after 3 half-lives.
What is 12.5 grams?
The process by which an unstable particle/nucleus emits a charged particle and/or energy.
What is radiation?
A sequence of radioactive decays in which an unstable nucleus transforms through multiple steps until reaching a stable isotope.
What is a decay series?
This nuclear process produces NO long-lived radioactive waste.
What is Fission?
Once our Sun exhausts its hydrogen fuel, it will expand and cool to become this type of star,
What is a Red Giant?
The amount of time it takes for C-14 (half-life 5730 yrs) to decay from 800kg to 50kg.
What is 22920 years?
A positively charged particle consisting of 2 protons and 2 neutrons emitted from an unstable atom.
What is an Alpha particle?
Lead-210 becomes Bismuth-210 through this type of decay process
What is Beta decay?
A fusion reactor converts the energy from nuclear reactions into this form first, then uses it to spin a turbine and generator to produce electricity.
What is heat energy?
Nuclear reaction - heat - mechanical energy(motion) - electrical energy
The stellar phenomenon that spreads heavy elements like iron and nickel throughout the galaxy.
What is a Supernova?
If 1/16 of the original substance is left and the half-life is 300 years, this is the age of the organism.
What is 1200 years?
Radiation listed in order of most to least penetrating.
What is Gamma, Beta, and Alpha radiation?
This is the end product after
Fr-223 undergoes one beta decay
followed by 3 alpha decays
What is Lead-211 (82 protons)
The sun combines two hydrogen isotopes—deuterium and tritium—through nuclear fusion to create this helium isotope.
What is Helium-4?
Stars with medium mass, like our Sun, will eventually evolve into this stage of the stellar life cycle.
What is a Black Dwarf?
Gold-198 has a half-life of 2.7 days. This is the amount of a 96g sample that will be left after 10.8 days.
What is 6 grams?
