Some important discoveries in scientific history that contributed to the development of nuclear chemistry are listed below. Briefly, describe each discovery, identify prominent scientists who contributed to it, and comment on the significance of the discovery to the development of this field.(a) 1905, theory of special relativity(b) 1932, (n, γ) reactions(c) 1939, fission reactions

(a)

Interpretation Introduction

Interpretation:

Theory of special relativity has to be commented.

Concept-Introduction:

In 1905 Albert Einstein determined that the laws of physics are the same for all non-accelerating observers, and that the speed of light in a vacuum was independent of the motion of all observers. This was the theory of Special relatively.

Explanation

Special relative theory explained about the space and time is linked for objects. These are moving at a constant speed in a straight line. One of its most famous aspects concerns objects moving at the speed of light, and the most famous equations in mathematics comes from special relative theory...

(b)

Interpretation Introduction

Interpretation:

Discovery, scientist who contributed to it and the significance has to be commented.

Concept-Introduction: The discovery of neutron by Sir James Chadwick, until 1932 the atom was known to consist of a positively charged nucleus. These are surrounded by enough negatively charged electrons to make the atom electrically neutral.

(c)

Interpretation Introduction

Interpretation:

Discovery, scientist who contributed to it and the significance has to be commented.

Concept-Introduction: In 13th January 1939 Frisch confirmed experimentally. And thus proving the barium results from his bombardment of uranium with neutrons was the product of nuclear fission.
