FLASHCARD QUESTION

Front

What is nuclear decay?

Back

Nuclear decay is the process by which an unstable atomic nucleus loses energy by emitting radiation, resulting in the transformation of the nucleus into a different element or isotope.

2.

FLASHCARD QUESTION

Front

What are the three main types of nuclear decay?

Back

The three main types of nuclear decay are alpha decay, beta decay, and gamma decay.

3.

FLASHCARD QUESTION

Front

What is alpha decay?

Back

Alpha decay is a type of nuclear decay in which an atomic nucleus emits an alpha particle (2 protons and 2 neutrons), resulting in a new element with a lower atomic number.

4.

FLASHCARD QUESTION

Front

What is beta decay?

Back

Beta decay is a type of nuclear decay in which a neutron in an atomic nucleus is transformed into a proton and an electron (beta particle), which is emitted from the nucleus.

5.

FLASHCARD QUESTION

Front

What is gamma decay?

Back

Gamma decay is a type of nuclear decay that involves the emission of gamma rays (high-energy photons) from an excited nucleus, without changing the number of protons or neutrons.

6.

FLASHCARD QUESTION

Front

What is an alpha particle?

Back

An alpha particle consists of 2 protons and 2 neutrons, and is emitted during alpha decay. It is positively charged and can be stopped by a sheet of paper.

7.

FLASHCARD QUESTION

Front

What is a beta particle?

Back

A beta particle is an electron or positron emitted during beta decay. It has a negative charge (in the case of beta-minus decay) and can penetrate materials more than alpha particles.
