Verified step by step guidance1
Identify the known particles in the nuclear reaction. The given reaction involves an electron (e), an alpha particle (α), and radon (Rn).
Recall the properties of the particles involved: an electron (β⁻) has a mass number of 0 and an atomic number of -1, an alpha particle (α) has a mass number of 4 and an atomic number of 2, and radon (Rn) is a noble gas with a specific atomic number and mass number.
Write the nuclear equation using the known particles. The equation should balance both the mass numbers and the atomic numbers on both sides.
Determine the missing species by ensuring the sum of the mass numbers and the sum of the atomic numbers are equal on both sides of the equation. This involves solving for the unknown particle that balances the equation.
Consider the options provided for the missing species and match them with the calculated values from the balanced equation to identify the correct missing species.
