5.4 Mastery Check v1: Natural Transmutation

Front

What is natural transmutation?

Back

Natural transmutation is the process by which an unstable atomic nucleus spontaneously transforms into a different element or isotope, often through radioactive decay.

What is an alpha particle?

Back

An alpha particle is a type of nuclear particle consisting of 2 protons and 2 neutrons, equivalent to a helium-4 nucleus, and is emitted during alpha decay.

What is a beta particle?

Back

A beta particle is a high-energy, high-speed electron or positron emitted during beta decay, which occurs when a neutron in an atomic nucleus transforms into a proton.

What is gamma radiation?

Back

Gamma radiation is a form of electromagnetic radiation of high energy emitted from a nucleus during radioactive decay, often accompanying alpha or beta decay.

What is the daughter nuclide in a decay process?

Back

The daughter nuclide is the product of the decay of a parent nuclide, resulting from processes like alpha or beta decay.

What is alpha decay?

Back

Alpha decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle, resulting in a decrease of 2 in atomic number and 4 in mass number.

What is beta decay?

Back

Beta decay is a type of radioactive decay in which a neutron is transformed into a proton, emitting a beta particle (electron or positron) and an antineutrino.

What is the significance of the atomic number in nuclear reactions?

Back

The atomic number determines the element's identity and changes during nuclear reactions, affecting the type of decay and the resulting daughter nuclide.
