the function of graphite in the first atomic reactor was to

absorb fast neutrons

in the fissioning of uranium, a chain reaction is caused by

ejected neutrons

when a lump of uranium is broken into smaller pieces, the total surface area of the lump

increases

Electrical forces inside a nucleus contribute nuclear

instability

Uranium-235, uranium-238, and uranium-239 are different

isotopes

compared to the mass of a uranium nucleus before splitting, the pieces it splits into have

less mass

in nuclear fission and nuclear fusion reactions, the amount of mass converted to energy is about

less than 1%

a nucleon has more mass when it is

outside the nucleus

a nucleon has more potential energy with respect to a nucleus when it is

outside the nucleus

when neptunium emits a beta particle, the result is

plutonium

U-235 and Pu-239 are both

radioactive isotopes fissionable isotopes heavier than lead

the different in the mass of a nucleon when outside an atomic nucleus compared to inside the nucleus depends on

the atomic number of the nucleus

which will leak more neutrons, two separate lumps of uranium or the same two lumps stuck together?

two separate lumps

in a breeder reactor

uranium is coverted into plutonium
