Nuclear Chemistry (Radioactivity/Half-Life)

Front

What is Nuclear Fusion?

Back

Nuclear fusion is the process in which two small atomic nuclei combine to form a larger nucleus, releasing energy in the process. It is the reaction that powers the sun.

Front

What is Half-Life?

Back

Half-life is the time required for half of the radioactive atoms in a sample to decay. It is a measure of the stability of a radioactive isotope.

What is the half-life of Iodine-131?

Back

The half-life of Iodine-131 is 8 days.

Front

What is Nuclear Fission?

Back

Nuclear fission is the process of splitting a large atomic nucleus into smaller nuclei, along with the release of energy.

Front

What is Beta Decay?

Back

Beta decay is a type of radioactive decay in which a beta particle (an electron or positron) is emitted from an atomic nucleus.

Front

What is an Alpha Particle?

Back

An alpha particle is a type of nuclear particle consisting of two protons and two neutrons, equivalent to a helium nucleus.

Front

What is a Gamma Ray?

Back

Gamma rays are high-energy electromagnetic radiation emitted during radioactive decay, having no mass or charge.

Front

What is the symbol for Beta Radiation?

Back

The symbol for beta radiation is β.

Front

What is the difference between Alpha and Beta Decay?

Back

Alpha decay involves the emission of alpha particles, while beta decay involves the emission of beta particles (electrons or positrons).

Front

What is the significance of the decay constant?

Back

The decay constant is a probability rate at which a radioactive isotope decays, related to its half-life.
