Question

If A is a radioactive element which emits an α - particle and produces ₁₀₄Rf ²⁵⁹. Write the atomic number and mass number of the element A

Answer 1

In α decay

_zX^A  `"αdecay"/263` x z - 2Y^A-4 + ₂He⁴ ( α decay)

106^x263 α decay 104 Rf²⁵⁹ + ₂He⁴

In element A having atomic number is 106 and the mass number is 263.
