An alpha decay is a radioactive decay where a positively charged particle containing two protons and two neutrons decay from a radioactive nucleus. This corresponds to a Helium nucleus (A=4,Z=2; where A corresponds to Mass Number and Z to atomic number).
If such a decay yields an alpha particle and a Na-24 nucleus let us summarize the following:
Sodium has an Atomic number 11 and Mass 24 & Helium 2 and Mass 4 respectively. Therefore total Mass of original nucleus is 28 and Atomic number is 13.
Aluminium has an atomic number 13. Hence the original identity of the nucleus is Aluminium-28 isotope.
