What is golden foil experiment about?

• Electrons are bombarding a golden foil and some of them go through, but others are scattered.

• Protons are bombarding a golden foil and some of them go through, but others are scattered.

• Alpha particles are bombarding a golden foil and some of them go through, but others are scattered.

• Beta particles are bombarding a golden foil and some of them go through, but others are scattered.

What was discovered by golden foil experiment?

• Atom is like a plum pudding where pudding is the positive particle and plums are the electrons

• Electron are orbiting around the nucleus

• Electrons are on different energy levels

• Atom is empty, and it has a positive nucleus

What is wrong in planetary model?

• If electrons loose energy, they would fall on the nucleus but they don's

• We can't say where electrons will be in different time like we can predict the position of the planets

• Electrons are orbiting around the nucleus.
