What is Nuclear Chemistry?

Back

Nuclear Chemistry is the study of the chemical and physical properties of elements as influenced by changes in the structure of the nucleus. It includes the study of radioactivity, nuclear processes, and properties of radionuclides.

What are the three main types of nuclear radiation?

Back

The three main types of nuclear radiation are Alpha particles, Beta particles, and Gamma rays.

Which type of nuclear radiation is the least penetrating?

Back

Alpha particles are the least penetrating type of nuclear radiation.

Front

Which type of nuclear radiation is the most penetrating?

Back

Gamma rays are the most penetrating type of nuclear radiation.

Front

What charge do Alpha particles carry?

Back

Alpha particles carry a +2 charge.

Front

What charge do Beta particles carry?

Back

Beta particles carry a -1 charge (electrons) or +1 charge (positrons).

What is the half-life of a radioactive substance?

Back

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

Front

If the half-life of a substance is 10 days, how much of the substance remains after 30 days?

Back

After 30 days, 1/8 of the substance remains.

Front

What is Electron Capture?

Back

Electron Capture is a type of radioactive decay in which an electron is captured by the nucleus, leading to a decrease in the atomic number.

Front

What is Beta Decay?

Back

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