Determine the missing products to complete the given decay scheme: ²⁵₁₃ Al ²⁵₁₂ Mg + ,?

Step-by-step solution

The given nuclear reaction is ²⁵₁₃ Al ²⁵₁₂ Mg + ,? In this decay, the mass number A remains constant at 25 , while the atomic number Z decreases from 13 to 12 . This indicates that a proton is converted into a neutron, which is characteristic of ⁺ decay (positron emission). The fundamental process for ⁺ decay is p n + e⁺ + , where e⁺ is a positron and is an electron neutrino. The complete decay equation is ²⁵₁₃ Al ²⁵₁₂ Mg + e⁺ + . The missing products are e⁺ and .
