Nuclear Equations Flashcard

Front

Beta radiation is ____________________

Back

an electron from the nucleus.

Front

Uranium-238 decays into Thorium-234 by emitting ..........

Back

an alpha particle

Front

Has the lowest penetrating power. Can only penetrate 0.05 mm into the body and can be stopped by a piece of paper or clothing.

Back

Alpha

Front

Has the highest penetrating power. Can penetrate our body. Even several cm thick of lead or several meters thick of concrete cannot stop all of it.

Back

Gamma

Front

Solve this equation for beta decay: 6^14C = ___ + -1^0e

Back

7^14N

Front

What is an alpha particle?

Back

An alpha particle consists of 2 protons and 2 neutrons, equivalent to a helium nucleus.

Front

What is the primary characteristic of gamma radiation?

Back

Gamma radiation is a high-frequency electromagnetic wave with no mass or charge.

Front

What is the difference between alpha and beta decay?

Back

Alpha decay emits an alpha particle, while beta decay emits a beta particle (electron) from the nucleus.

Front

What is the equation for alpha decay of Uranium-238?

Back

238^92U → 234^90Th + 4^2He

Front
