Suppose Rutherford had not seen any alpha particles deflected back from the gold foil. How would this most likely have affected scientific understanding of the structure of an atom?
Aplus answer
It would have taken scientists longer to discover protons. A+
Aplus answer
If Rutherford had not observed any deflection of alpha particles, it would suggest that the positive charge in an atom is spread out uniformly, rather than concentrated in a small nucleus. This would likely lead to the continued acceptance of the plum pudding model of the atom, proposed by J.J. Thomson, where positive charge is distributed evenly throughout the atom. The discovery of the nucleus and the planetary model of the atom would have been delayed.

What did Rutherford call the region that deflected the alpha particles?
Rutherford called the region in the gold foil experiment that deflected alpha particles the "nucleus." He discovered that the positive charge and most of the mass of an atom were concentrated in this small, dense region.
When Rutherford performed his metal foil experiment did the alpha particles pass straight through the foil or bounce back?
In Rutherford's metal foil experiment, some alpha particles passed straight through the foil, while others were deflected at various angles. A small fraction of the alpha particles even bounced back towards the source. This led Rutherford to conclude that atoms have a small, dense nucleus at their center.
What did Rutherford observe that suprised him?
Rutherford observed that some alpha particles fired at a thin sheet of gold foil were deflected back at very large angles, signaling that the positive charge in an atom is concentrated in a very small, dense nucleus. This discovery contradicted the prevailing model of the atom at the time, known as the plum pudding model, and laid the foundation for the modern understanding of atomic structure.
Why did some of the particles get deflected in Rutherford experiment?
A beam of alpha particles shot through a thin thin thin gold foil will occasionally have a few coming close to the nucleus of a gold atom - and as alpha particles have the same charge as the nucleus there is a repulsive force, which forces the particle from its original course. To keep a graduate student busy (I believe it was Marsden) Rutherford asked him to investigate if there was any particles that got deflect through an angle larger than 90'. (A preposterous notion) An to his great surprise there was.
How did Rutherford know the nucleus was positively charged?
Rutherford conducted the famous gold foil experiment, where he observed that some alpha particles were deflected back at large angles when they passed through thin gold foil. This led him to propose that the positive charge of an atom is concentrated in a small, dense region called the nucleus.

Who explained the behavior of positively charged particles being deflected from a metal foils as the nucleus?
ernest Rutherford
What is the main observation of the Rutherford's experiment?
Most of the particles went through the foil, but some were deflected
Who discovered the nucleus using his gold foil?
Rutherford by bombarding gold foil with positively charged particles and noting that some particles were widely deflected.
What technology helped Ernest Rutherford discover the atom?
Ernest Rutherford used the technology of radioactivity and conducted the famous gold foil experiment to discover the structure of the atom. By directing alpha particles at a thin gold foil, he observed how they were deflected, which led to the understanding that atoms have a small, positively charged nucleus at their center.
Who discovered the nucleus using his gold foil experiment?
Ernest Rutherford is the scientist who discovered the nucleus through his gold foil experiment in 1909. He observed that most of the alpha particles passed through the foil, but some were deflected, leading him to propose the existence of a dense, positively charged nucleus at the center of an atom.
What is the explanation for the scattering experiment of Rutherford?
Rutherford's scattering experiment involved firing alpha particles at a thin gold foil. Most alpha particles passed through undeflected, but some were deflected at large angles, and a few even bounced directly back. This led to the conclusion that atoms have a small, dense nucleus at their center, with the rest of the atom being mostly empty space.
What evidence led Rutherford to conclude that an atom is mostly empty space?
The experimental evidence led Rutherford to conclude that an atom is mostly empty space because most of the particles weren't deflected off of the gold foil in his experiment.
Why were few alpha particles deflected?
some of alpha particles were deflected through an angle of 90 degree
When Rutherford performed his metal foil experiment did the alpha particles pass straight through the foil or bounce back?
In Rutherford's metal foil experiment, some alpha particles passed straight through the foil, while others were deflected at various angles. A small fraction of the alpha particles even bounced back towards the source. This led Rutherford to conclude that atoms have a small, dense nucleus at their center.
