The reaction involves potassium-38 and a proton, resulting in calcium-38. The missing particle X must balance the atomic and mass numbers. The atomic number increases by 1 (from 19 to 20), and the mass number remains the same (38). This indicates the emission of a neutron, which has a mass number of 1 and an atomic number of 0.
