Answer: The daughter nucleus produced when 188 Hg undergoes positron emission is gold.
Explanation:
Positron emission: It is a type of decay process, in which a proton gets converted to neutron and an electron neutrino. This is also known as -decay. In this the mass number remains same.
General representation of an element is given as: [tex]_Z^A\textrm{X}[/tex]
where,
Z represents Atomic number
A represents Mass number
X represents the symbol of an element
The chemical equation for positron emission is represented as:
[tex]_Z^A\textrm{X}\rightarrow _{Z-1}^A\textrm{Y}+_{+1}^0e[/tex]
[tex]_{80}^{188}\textrm{Hg}\rightarrow _{79}^{188}\textrm{Au}+_{+1}^0e[/tex]
