When Iodine-131 emits a β particle will produce Xe-131

<h3>Further explanation </h3>

Radioactivity is the process of unstable isotopes to stable isotopes by decay, by emitting certain particles,

alpha α particles ₂He⁴
beta β ₋₁e⁰ particles
gamma particles ₀γ⁰
positron particles ₁e⁰
neutron ₀n¹

So for reaction Iodine-131 :

$\tt _{53}^{131}I\rightarrow _{-1}^0\beta +_{54}^{131}Xe$
