Flashcard: Typer of Particles and Nuclear Equations

Front

What is gamma radiation?

Back

Gamma radiation is the highest-energy type of radioactive decay, consisting of high-energy photons emitted from the nucleus of an atom.

Front

What happens to an element after alpha decay?

Back

After alpha decay, the element loses 2 protons and 2 neutrons, resulting in a new element with a lower atomic number.

Front

What is an alpha particle?

Back

An alpha particle is a type of nuclear radiation consisting of 2 protons and 2 neutrons, equivalent to a helium nucleus.

Front

What is beta radiation?

Back

Beta radiation consists of beta particles, which are high-energy, high-speed electrons or positrons emitted from a nucleus during radioactive decay.

Front

What is the most penetrating form of radiation?

Back

Gamma radiation is the most penetrating form of radiation, capable of passing through most materials.

Front

What are the products of U-238 decay?

Back

The products of U-238 decay include an alpha particle and 234-Th (Thorium-234).

Front

What is a positron?

Back

A positron is the antimatter counterpart of an electron, with the same mass but a positive charge.

Front

What is the difference between alpha and beta radiation?

Back

Alpha radiation consists of heavy particles (2 protons and 2 neutrons), while beta radiation consists of lighter particles (electrons or positrons).

Front

What is a nuclear equation?

Back

A nuclear equation represents the decay of a radioactive isotope, showing the initial and final elements along with emitted particles.

Front

How does gamma radiation differ from alpha and beta radiation?

Back

Gamma radiation is electromagnetic radiation with no mass or charge, while alpha and beta radiation consist of particles.
