Question

What is the daughter nucleus produced when 63 Zn undergoes electron capture? Replace each question mark with the appropriate integer or symbol.

Answer 1

Answer: The daughter nuclei is $_{29}^{63}\textrm{Cu}$

Explanation:

Electron capture is defined as the process in which an electron is drawn to the nucleus where it combines with a proton to form a neutron and a neutrino particle.

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

The chemical equation for the reaction of electron capture of Zinc-63 nucleus follows:

$_{30}^{63}\textrm{Zn}+e^-\rightarrow _{29}^{63}\textrm{Cu}+\gamma e$

The parent nuclei in the above reaction is Zinc-63 and the daughter nuclei produced in the above reaction is copper-63 nucleus.

Hence, the daughter nuclei is $_{29}^{63}\textrm{Cu}$
