Flashcard --- Nuclear Decay

Front

What is nuclear fission?

Back

Nuclear fission is the process in which a heavy nucleus splits into two lighter nuclei, releasing energy.

Front

What is an alpha particle?

Back

An alpha particle is a type of nuclear particle that consists of 2 protons and 2 neutrons.

Front

What is beta decay?

Back

Beta decay is a type of radioactive decay in which a beta particle (an electron or positron) is emitted from an atomic nucleus.

Front

What are control rods used for in a nuclear reactor?

Back

Control rods are used to slow down the rate of nuclear reactions by absorbing neutrons.

Front

What is the role of a coolant in a nuclear reactor?

Back

A coolant is used to remove heat from the reactor core and transfer it to a steam generator.

Front

What is radioactive decay?

Back

Radioactive decay is the process by which an unstable atomic nucleus loses energy by emitting radiation.

Front

What is a beta particle?

Back

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

Front

What is positron emission?

Back

Positron emission is a type of radioactive decay in which a positron (the antimatter counterpart of an electron) is emitted.

Front

What is electron capture?

Back

Electron capture is a process in which an electron is captured by the nucleus, leading to a decrease in the number of protons.

Front

What is the significance of the atomic number?

Back

The atomic number is the number of protons in the nucleus of an atom, determining the element's identity.
