SCI 206 - Modern Physics || CORRECTLY SOLVED!!
Is mixing sodium and chlorine a form of atomic bomb? correct answers yup
What has the most mass in an atom? correct answers nucleus which has protons and neutrons
How much bigger is the nucleus compared to an electron? correct answers it is 2000 times
bigger.. 99.975% of sodiums mass is form the nucleus.
What is nuclear force? correct answers When 2 things are touching its harder for them to be
moved apart.
What is electrostatic repulsion? correct answers Positive charges in the nucleus want to break
free because they each have the same charge
radioactive decay? correct answers When things inside nucleus eventually breaks away from the
nuclear force
More neutrons added in the nucleus does what? correct answers reduces the electrostatic
repulsion of protons
nuclear fusion? correct answers When you add more nucleons to an atom. Hard to do because of
the strong electrostatic repulsion but once done, the nuclear force would hold it together.
This releases a large potential energy
Not this processes also consumes large amount of energy because you have to add energy to add
nucleons.
nuclear fission? correct answers When adding neutrons to the nucleus causes it to split apart and
form a new fission atom and a free energy atom.
This releases a large amount of large potential energy.
What are isotopes? correct answers Nucleus that only differ in the number of neutrons
Super critical mass? correct answers When mass is so great you get an explosive chain reaction
How did the fission bomb work? correct answers Uranium 235 was places at the end of the
bomb.. and bullet was fired from one side and it shot a neutron to the right side. Once hit, it
started a chain reaction.
How do fusion bombs work? correct answers You can't have fusion on earth (happens in sun)
unless temps are high.
So you use a fission bomb to create high temps
Then this causes high speeds in fusion H2 and H3 atoms causing them to form he and release
energy.
