an atom with too many neutrons or too many protons
What is an unstable nucleus
100
a sequence of reactions where are reactive product or by-product causes additional reactions to take place
What is a chain reaction
100
an equation for radioactive decay using half-life
What is:
N(t)= No(1/2)
N(t)= No^-t/1
N(t)=Noe^- wavelength * t
100
Miss Weirman's fish is named
What is Moo
100
Miss Weirman likes
What is pens
200
the spontaneous change or disintegration of an unstable nuclei that occur spontaneously or as a result of electron capture.
What is radioactive decay
200
the name of Miss. Weirman's dog
What is Gunner!
200
name one nuclear equation of decay
What is
N(t)= No(1/2)
N(t)= No^-t/1
N(t)=Noe^- wavelength * t
200
a process that creates a nuclear chain reaction, usually done by firing a neutron into a uranium atom. The uranium atom absorbs the neutron and splits into two lighter elements with additional neutrons. This sets off a chain reaction with other uranium atoms and releases vast amounts of energy.
What is a fission reaction
200
atom, hydrogen and/or nuclear bombs
What is an unwanted chain reaction
300
the period of time it takes for the amount of a substance undergoing decay to decrease by half
What is a half-life
300
nuclear fission is key in reactors and bombs
What is nuclear fission used today
300
name three types of radioactive decay
What is alpha radiation, beta radiation, and gamma radiation
300
the Earth operated a natural fission reactor in a uranium deposit in North Africa about two billion years ago.
What is an example of a fission reaction
300
DNA template, digestive system, etc.
What is when a chain reaction is desired
400
equal to the reciprocal value of the average life time (t)
What is the decay constant
400
stars (including the sun)
What is nuclear fission observed in nature
400
a radioactive nucleus with to many protons or neutrons that create an unstable atom
What is why a nucleus can be unstable
400
a nuclear process in which two light nuclei combine to form a single heavier nucleus
What is a fusion reaction
400
A nuclear chain reaction occurs when one nuclear reaction causes an average of one or more nuclear reactions, thus leading to a self-propagating series of nuclear to chain reactions
What is how a nuclear reaction can become a chain reaction
500
a process that occurs in the nucleus once the atom loses subatomic particles to the degree that its properties are altered
What is a nuclear reaction
500
name three radioactive elements
What is Tc, Pm, Po, At, Rn, Fr, Ra, Ac, Th, Pa, U, Np, Pu, Am, Cm, Bk, Cf, Es, Fm, Md, No, Lr, Rf, Db, Sg, Bh, Hs, Mt, Ds, Rg, Cn, Uut, Uuq, Uup, Uuh, Uur, Uuo
500
Miss. Wierman's soon to be last name
What is Robinson
500
improvement in thermonuclear weapons and in the future, nuclear reactors will be the reaction between two different hydrogen isotopes to form an isotope of helium
What is an example of a fusion reaction
500
is a natural science that involves the study of matter[1] and its motion through space time, along with related concepts such as energy and force
