Question

How do you complete the following alpha decay reaction?

Answer 1

When a radioactive nuclide ejects an alpha particle,it's mass number decreases by 4 and atomic number decreases by 2 such that the position of the daughter nuclide is two places behind in the periodic table as compared to parent nuclide.

When a radioactive nuclide ejects an alpha particle,it's mass number decreases by 4 and atomic number decreases by 2 such that the position of the daughter nuclide is two places behind in the periodic table as compared to parent nuclide.consider radioactive nuclei and X with mass number A and atomic number Z that it ejects and Alpha particle according to above law the mass number of daughter nuclide add will be A - 4 and atomic number Z - 2.
