Pt195 having 78 atomic number is the daughter nucleus produced when Au195 undergoes electron capture.
An unstable isotopes can undergoes radioactive decay to form a more stable isotopes . Initial isotopes is called parent nuclide and the resultant isotopes from radioactive decay is called the daughter nuclide There are several radioactive decay like alpha decay , beta decay , gamma decay , electron capture etc .
In electron capture , the atom have only one less which is daughter isotopes than electron than atomic number of parent isotopes.
