Capitolo 21, Problema 15a
Decay of which nucleus will lead to the following products: (a) bismuth-211 by beta decay?
Guida verificata passo dopo passo1
Identify the process of beta decay: In beta decay, a neutron in the nucleus is converted into a proton, and a beta particle (electron) is emitted.
Recognize that the atomic number increases by 1 during beta decay because a neutron is converted into a proton.
Determine the original nucleus: Since bismuth-211 is the product, and its atomic number is 83, the original nucleus must have an atomic number of 82.
Identify the element with atomic number 82, which is lead (Pb).
Conclude that the decay of lead-211 (Pb-211) by beta decay will result in bismuth-211 (Bi-211).

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Beta Decay
Beta decay is a type of radioactive decay in which a beta particle (an electron or positron) is emitted from an atomic nucleus. In beta-minus decay, a neutron is transformed into a proton, resulting in the emission of an electron and an antineutrino. This process increases the atomic number of the nucleus by one while keeping the mass number unchanged, leading to the formation of a new element.

Beta Decay
Nuclear Transmutation
Nuclear transmutation refers to the process by which one element or isotope is converted into another through nuclear reactions. In the context of beta decay, the transformation of a neutron into a proton changes the identity of the element, as the atomic number increases. This concept is fundamental in understanding how elements can change and form new isotopes during radioactive decay.

Isotopes
Isotopes are variants of a particular chemical element that have the same number of protons but different numbers of neutrons, resulting in different mass numbers. For example, bismuth-211 has 83 protons and 128 neutrons. Understanding isotopes is crucial for identifying the products of nuclear reactions, as the decay of one isotope can lead to the formation of another with distinct nuclear properties.
