### Radioactive Decay Question#### Question 10 of 22:Radium (A = 226, Z = 88) decays to Radon (A = 222, Z = 86) with a half-life of 1600 years. What type of decay is this?- **alpha**- **beta-minus**- **beta-plus**- **gamma**- **not enough information given****Explanation:**- **Alpha Decay**: In alpha decay, an atomic nucleus emits an alpha particle (2 protons and 2 neutrons). This decreases the atomic mass number (A) by 4 and the atomic number (Z) by 2, resulting in A = 222 and Z = 86.- **Beta-minus Decay**: In beta-minus decay, a neutron is converted into a proton, increasing the atomic number (Z) by 1, but the atomic mass number (A) remains the same.- **Beta-plus Decay**: In beta-plus decay, a proton is converted into a neutron, decreasing the atomic number (Z) by 1, but the atomic mass number (A) remains the same.- **Gamma Decay**: In gamma decay, there is no change in the atomic mass number (A) or atomic number (Z); it only releases energy.Given the information, the decay of Radium to Radon, with a decrease in both atomic mass number (A) and atomic number (Z) by 4 and 2 respectively, is indicative of **alpha decay**.

in this question we discuss about decay of radioactive substances.

Concept explainers

Nuclear Reactions

Nuclear reactions are processes in which the fundamental characteristics of a nucleus changes. They change into a completely different nucleus. These processes occur naturally in an unstable nucleus. Bombarding an energetic particle can induce nuclear reactions. In this article, both the naturally occurring nuclear reactions are termed as radioactive decay and the induced nuclear reactions are further categorized as nuclear fission and nuclear fusion.
