Question

For the following reaction, the particle 'x' is ₆C¹¹ → ₅B¹¹ + β + X ______.

Options

• proton

• neutrino

• anti neutrino

• neutron

Answer 1

For the following reaction, the particle 'x' is ₆C¹¹ → ₅B¹¹ + β + X neutrino.

Explanation:

In the reaction ₅B¹¹ → ₆C¹¹ + β⁺ + X, particle X must be a neutrino because after conserving atomic number (Z = 0) and mass number (A = 0), lepton number conservation requires a neutrino to be emitted alongside the positron (β⁺).
