The synthesis of livermorium:(a) Lv-296 is made from the collision of a relatively light atom with curium-248. What is the lighter particle?(b) Lv-296 is not stable, decaying to Lv-293. What particles are emitted in this process?

(a)

Interpretation Introduction

Interpretation:

The lighter particle that formed from collision has to be predicted.

Concept-Introduction:

Nuclear fusion: A reaction in which two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles.

Explanation

C96248m+C2048aL116296v

The bombardment of Curium with unknown particle produces Livermorium. The unknown particle is predicted by the rule that says the atomic and mass number must be equal.

(b)

Interpretation Introduction

Introduction:

The lighter particle that formed from collision has to be predicted.

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.
