Deuterium nuclei ( H 1 2 ) are particularly effective as bombarding particles to carry out nuclear reactions. Complete the following equations:(a) C 48 114 d +  H 1 2 →  ? +  H 1 1 (b) L 3 6 i +  H 1 2 →  ? +  n 0 1 (c) C 20 40 a +  H 1 2 →   K 19 38  +  ? (d) ?  +  H 1 2 →   Z 30 65 n + γ

(a)

Interpretation Introduction

Interpretation:

The unknown particle in the given nuclear process has to be completed.

Concept Introduction:

Balancing nuclear reaction equation: The balanced nuclear reaction should conserve both mass number and atomic number.

• The sum of the mass numbers of the reactants should be equal to the sum of mass numbers of the products in the reaction.
• The sum of atomic numbers (or the atomic charge) of the reactants should be equal to the sum of atomic numbers (or the atomic charge) of the products in the reaction.
Explanation

The bombardment of Deuterium nuclei with Cadmium-114, produce an unknown particle and a proton particle. The unknown particle is predicted by the rule that says the atomic and mass number must be equal.
