Answer :
Answer: Mercury-194 is an unstable isotope and hence is radioactive.
Explanation: Mercury-194 is an isotope of mercury, having formula [tex]_{80}^{194}\textrm{Hg}[/tex]
Number of protons in this isotope = 80
Number of neutrons in this isotope = 114
This isotope is radioactive in nature and under decay process by Electron Capture.
Electron capture reactions are the reactions in which a proton in a nucleus absorbs an electron and convert it into neutron. The resulting nucleus will have a decreased atomic number and same atomic mass.
Reaction for electron capture of mercury-194 follows:
[tex]_{80}^{194}\textrm{Hg}+_{-1}^0\textrm{e}\rightarrow _{79}^{194}\textrm{Au}[/tex]
The "mercury-194" is a kind of isotope which is untastable and radioactive.
What is isotope?
Isotopes may be members of the very same element's family but also have variable counts of neutrons despite roughly the identical count of protons.
What is radioactive?
An unstable nucleus of an atom releases energy through radiation in a process known as radioactive decay.
Therefore, the "mercury-194" is a kind of isotope which is untastable and radioactive.
