Question

Name the metal selected by Rutherford for his α -particle experiment Give reason.

Answer 1

Answer:

Because gold is the most malleable metal and he wanted a thinnest layer as possible .the gold sheet was used around 1000 atoms thick ..

Answer 2

Rutherford's experiment - Gold

Explanation:

In Rutherford's experiment to show the existence of nucleus in an atom, the alpha-particles were exposed on the surface of a gold foil. He observed that more than 99% of these particles were able to go straight and pass through the gold atoms. Gold was selected because it is the most malleable metal and Rutherford wanted the most thin layer of gold for the atoms to pass through.
