when i 131 emits a beta particle what nuclide is produced

when iodine-131 under a beta decay,  there is a decreases in its number of neutrons and an increases in the number of protons, the atomic number increases by one, and the nuclide formed is xenon-131.

as shown in the equation

¹³¹₅₃I → ¹³¹₅₄Xe + ⁰_-1e
