Nuclear Equations

Front

What is a nuclear equation?

Back

A nuclear equation is a representation of a nuclear reaction, showing the initial and final nuclei and particles involved in the reaction.

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 a beta particle?

Back

A beta particle is a high-energy, high-speed electron or positron emitted during radioactive decay.

Front

What is a gamma ray?

Back

A gamma ray is a form of electromagnetic radiation of high energy and short wavelength, emitted from a nucleus.

Front

What does the symbol -1 0 e represent?

Back

The symbol -1 0 e represents a beta particle.

Front

What is the most penetrating form of radiation?

Back

Gamma radiation is the most penetrating form of radiation.

Front

How does a nuclear reaction differ from a chemical reaction?

Back

A nuclear reaction involves changes in an atom's nucleus, while a chemical reaction involves changes in the arrangement of electrons.

Front

What is the conservation of mass in nuclear reactions?

Back

In nuclear reactions, the total mass and energy are conserved, although mass can be converted to energy according to Einstein's equation E=mc².

Front

What is the role of neutrons in nuclear reactions?

Back

Neutrons can initiate nuclear reactions and help stabilize the nucleus by reducing repulsion between protons.

Front

What is a fission reaction?

Back

A fission reaction is a nuclear reaction in which a heavy nucleus splits into smaller nuclei, releasing energy.
