FLASHCARD QUESTION

Front

What is a nuclear equation?

Back

A nuclear equation represents a nuclear reaction, showing the transformation of atomic nuclei and the particles involved.

2.

FLASHCARD QUESTION

Front

What is an alpha particle?

Back

An alpha particle is a type of nuclear radiation consisting of 2 protons and 2 neutrons, identical to a helium nucleus, represented as \( \text{ }^{4}_{2}\text{He} \).

3.

FLASHCARD QUESTION

Front

What is a beta particle?

Back

A beta particle is a high-energy, high-speed electron or positron emitted during radioactive decay, represented as \( \text{ }^{0}_{-1}e \) for electrons.

4.

FLASHCARD QUESTION

Front

What is gamma radiation?

Back

Gamma radiation is a form of electromagnetic radiation emitted from a nucleus during radioactive decay, represented as \( \gamma \).

5.

FLASHCARD QUESTION

Front

What is the conservation of mass in nuclear reactions?

Back

In nuclear reactions, the total mass and energy are conserved, meaning the sum of the masses of the reactants equals the sum of the masses of the products.

6.

FLASHCARD QUESTION

Front

What is the difference between fission and fusion?

Back

Fission is the splitting of a heavy nucleus into smaller nuclei, releasing energy, while fusion is the combining of light nuclei to form a heavier nucleus, also releasing energy.

7.

FLASHCARD QUESTION

Front

What is half-life?

Back

Half-life is the time required for half of the radioactive nuclei in a sample to decay.
