The daughter isotope of ¹⁸⁰Hg when it undergoes alpha-emission is ¹⁷⁶Pt.

Question

Quizplus · Accepted Answer

When an alpha particle (which is a helium nucleus) is emitted, it consists of two protons and two neutrons. This means that the atomic number of the parent nucleus decreases by 2 while the mass number decreases by 4. In this case, the parent nucleus is Hg-118, which has an atomic number of 80 and a mass number of 118. After losing an alpha particle, the resulting nucleus has an atomic number of 78 (Pt) and a mass number of 114. Therefore, the daughter isotope is Pt-114, which is ¹⁷⁶Pt.
