Chapter 24, Problem 24.117P

Interpretation Introduction

Interpretation:

Decay series of ${}_{92}^{239}U$ has to be given where it first undergo ${\beta }^{-}$ emission, then again emission of ${\beta }^{-}$ and again two consecutive alpha emission. Also natural series that can be started by this sequence has to be given.

Concept Introduction:

Nuclear reaction: A nuclear reaction in which a lighter nucleus fuses together into new stable nuclei or a heavier nucleus split into stable daughter nuclei with the release of large amount of energy.

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.
