LIFE SCIENCE

Detailed explanation-1: -The gold foil experiment was designed by Rutherford . In his experiment, the particles were made to come down on a thin gold foil. Alpha particles are made up of two protons and two neutrons tightly bound together which is identical to Helium-4. Many of the particles passed linearly through the gold foil.

Detailed explanation-2: -Physicist Ernest Rutherford established the nuclear theory of the atom with his gold-foil experiment. When he shot a beam of alpha particles at a sheet of gold foil, a few of the particles were deflected. He concluded that a tiny, dense nucleus was causing the deflections.

Detailed explanation-3: -The discovery of radioactivity in 1896 led to a series of more in-depth investigations. In 1899 Ernest Rutherford demonstrated that there were at least two distinct types of radiation: alpha radiation and beta radiation. He discovered that radioactive preparations gave rise to the formation of gases.
