Chapter 19, Problem 19.23QP

Interpretation Introduction

Interpretation: factors leads to nuclear decay should be discussed.

Concept Introduction:

• Radio active life-it refers to the amount of time taken by completion of half of its original isotope to decay. The rate of decay is a fixed rate called half-life.
• Half-life used in carbon dating-technique for the age calculation of dead wood fossil, monument old tree etc.
• The half-life period s are determined by considering carbon dating technique.
• Carbon dating uses the half-life of carbon-14 to find the approximate age of an object. It’s may be 40.000 year old or younger.

  Radioactive isotope: An atom in a chemical compound is replaced by another atom, of the same chemical element. This is the principle behind the radioactive tracers.

  Titanium is the example of radioactive isotope.

The power of the technique of radioactive decay is much greater than the chemical reaction.

To determine: factors enhance to nuclear decay is explained
