Flashcard Nuclear Chem & Electron Configurations & Orbitals Level 1

Front

What is Half-Life in nuclear chemistry?

Back

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

Front

What is the product of the nuclear reaction: ₈₅²⁰⁹At --> ___ + ₂⁴He?

Back

₈₃²⁰⁵Bi

Front

What is nuclear fusion?

Back

A nuclear reaction where multiple nuclei combine under high heat and pressure to form one large nucleus, releasing vast amounts of energy.

Front

What is radiation in the context of nuclear chemistry?

Back

The process by which an unstable nucleus decays and releases energy and particles.

Front

What is the correct equation for U-238 alpha decay?

Back

True.

Front

What is nuclear fission?

Back

A nuclear reaction where a large nucleus splits into smaller nuclei, releasing energy.

Front

What is a chain reaction in nuclear chemistry?

Back

A series of reactions where the products of one reaction initiate further reactions.

Front

What is an alpha particle?

Back

A type of radiation consisting of 2 protons and 2 neutrons, equivalent to a helium nucleus.

Front

What is a beta particle?

Back

A high-energy, high-speed electron or positron emitted during radioactive decay.

Front

What is the difference between fission and fusion?

Back

Fission is the splitting of a nucleus, while fusion is the combining of nuclei.
