Explanation / Answer

from the given data

gallium-67 undergoes decay by means of electron capture

we know that

electron is 0 e -1

so

atomic number reduced by 1

so

atomic number of product is 30

we know that

zinc has atomic number 30

so

the nuclear equation is

67 Ga 31 + 0 e -1 ---> 67 Zn 30 + 0 Y 0

we can see that

mass number of product is 67

atomic number of product is 30

name of the product nuclide is zinc -67
