Question

What is the daughter nucleus produced when 188 Hg Hg188 undergoes positron emission? Replace each question mark with the appropriate integer or symbol.

Answer 1

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: $_Z^A\textrm{X}$

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:

$_Z^A\textrm{X}\rightarrow _{Z-1}^A\textrm{Y}+_{+1}^0e$

$_{80}^{188}\textrm{Hg}\rightarrow _{79}^{188}\textrm{Au}+_{+1}^0e$
