1.
nuclear energy is...
a)
when atoms bond.
b)
the energy in the electron shell.
c)
when atoms absorb radioactive rays.
d)
the energy that holds protons and neutrons in the nucleus.
2.
nuclear energy can be obtained by...
a)
an atom decaying.
b)
bonding, when atoms share electrons.
c)
an atom releasing an omega molecule.
d)
fission, the splitting of an atom.
3.
an advantage of nuclear energy is that...
a)
it reduces energy generated from fossil fuels.
b)
it can produce gases that produce endorphins.
c)
it can be made into a delicious cake.
d)
it can be used to create beverages that make you grow taller.
4.
a disadvantage of nuclear energy is that...
a)
it can become a toxic cake.
b)
it can take years to eliminate nuclear waste's radioactivity and waste.
c)
it can't be used to achieve desired results.
d)
it emits greenhouse gases.
5.
fission is...
a)
when atoms are left alone to decay and then are used to make nuclear juice.
b)
when atoms bond together to create larger atoms.
c)
when an atom generates radioactive rays.
d)
when atoms are split into smaller atoms, releasing energy.
6.
this atom is used in nuclear energy...
a)
C-14
b)
Co-59
c)
H-2
d)
U-235
7.
a U-235 atom is necessary for nuclear energy because...
a)
it emits omega molecules that power a turbine.
b)
uranium can undergo induced fission.
c)
uranium is a small and delicate atom.
d)
uranium is a immortal atom.
8.
in a nuclear reactor...
a)
atoms fuse, emitting energy.
b)
atoms decay, emitting heat.
c)
a controlled fission chain reaction occurs.
d)
a uncontrolled fusion chain reaction occurs.
9.
a fission chain reaction is...
a)
when a U-235 atom absorbs a neutron then splits in half, releasing energy and 2-3 neutrons that then split the results of the U-235 atom, and again and again.
b)
when an alpha particle is released by fusion and then fuses with an omega molecule emitting heat and radiation.
c)
when a electron grows to be the size of an electron and splits a U-235 atom in two again and again.
d)
when a molecules is split by a proton and releases radioactivity that powers a turbine to release heat.
10.
this formula is used to describe the slight loss of mass in an atom that generates heat energy...
a)
E=mc^5
b)
E=vc^2
c)
E=mt^7
d)
E=mc^2
