Answer 2

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

Further explanation

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`
