Nuclear Chemistry

Front

What is nuclear fusion?

Back

Nuclear fusion is the process where two or more atomic nuclei combine to form a single, larger nucleus, releasing energy in the process.

Front

What is the charge of beta particles?

Back

Beta particles have a -1 charge.

Front

What type of nuclear radiation is emitted when a beta particle is released?

Back

Beta radiation is emitted.

Front

How much of a substance remains after one half-life?

Back

After one half-life, half of the original amount of the substance remains.

Front

What is nuclear fission?

Back

Nuclear fission is the process where a large atomic nucleus splits into two or more smaller nuclei, accompanied by the release of energy.

Front

What is the half-life of a radioactive substance?

Back

The half-life is the time required for half of the radioactive atoms in a sample to decay.

Front

What is an example of a radioactive isotope used in medicine?

Back

Iodine-131 is an example of a radioactive isotope used in medical treatments.

Front

What is gamma radiation?

Back

Gamma radiation is a type of high-energy electromagnetic radiation emitted during radioactive decay.

Front

What happens to the mass number during nuclear fission?

Back

The mass number decreases as the large nucleus splits into smaller nuclei.

Front

What is the difference between alpha and beta radiation?

Back

Alpha radiation consists of helium nuclei (2 protons and 2 neutrons), while beta radiation consists of electrons or positrons.
