Nuclear Chemistry

Front

What is nuclear fusion?

Back

Nuclear fusion is the process of joining two atomic nuclei to form a heavier nucleus, releasing energy in the process. It occurs naturally in stars, including the Sun.

Front

What is nuclear fission?

Back

Nuclear fission is the process of splitting an atomic nucleus into two or more smaller nuclei, along with the release of energy.

What type of nuclear radiation is emitted during beta decay?

Back

Beta radiation is a type of nuclear radiation that consists of beta particles, which are high-energy, high-speed electrons or positrons emitted by certain types of radioactive nuclei.

What is the half-life of a radioactive isotope?

Back

The half-life of a radioactive isotope is the time required for half of the radioactive atoms in a sample to decay into a different element or isotope.

Front

What is the half-life of iodine-131?

Back

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

Front

What occurs naturally in the center of stars like the Sun?

Back

Nuclear fusion occurs naturally in the center of stars like the Sun.

Front

What is a chain reaction in nuclear chemistry?

Back

A chain reaction is a series of reactions where a reactive product or by-product causes additional reactions to occur, commonly seen in nuclear fission.

Front

What are alpha particles?

Back

Alpha particles are a type of nuclear radiation consisting of two protons and two neutrons, essentially a helium nucleus.

Front

What are gamma rays?

Back

Gamma rays are high-energy electromagnetic radiation emitted during radioactive decay, often accompanying alpha and beta decay.

Front

What is the difference between fusion and fission?

Back

Fusion is the joining of atomic nuclei, while fission is the splitting of atomic nuclei.
