Most alpha particles passed directly through the gold atoms undisturbed what does this evidence suggest about the structure of the gold atoms?

I think that there were empty spaces in the model.

The fact that most alpha particles passed directly through the gold atoms suggests that the majority of an atom's mass is concentrated in a small, dense nucleus. This implies that the rest of the atom consists of mostly empty space with electrons moving around the nucleus.

What is the best evidence that the particles of matter are constantly moving comes from?
The best evidence that particles of matter are constantly moving comes from the observation of Brownian motion. This is the random movement of particles suspended in a fluid, caused by collisions with molecules of the surrounding medium. The continuous, random motion of these particles provides strong evidence for the kinetic theory of matter.
Brownian motion is evidence of?
Brownian motion is evidence of the random movement of particles suspended in a fluid, caused by collisions with the fluid's molecules. This phenomenon served as crucial evidence supporting the kinetic theory of matter, which states that all matter is made up of particles in constant motion.
Why do you think Thomson hypothesized that electrons must come from inside an atom?
Thomson had two pieces of evidence: 1- No matter what metal he used for the disk, the particles produced were indentical. 2- The particles had about 1/2000 the mass of a hydrogen, the lightest atom. These experiments provided the first evidence that atoms are made of even smaller particles.
Explain why diffusion is evidence for particle models?
Diffusion occurs because particles move randomly in all directions until they are evenly distributed. This can be explained by the particle model, which states that matter is made up of tiny particles that are constantly in motion. The movement of particles in diffusion supports the idea that substances are composed of particles that are constantly moving.
What are the 2 processes which provides evidence for motion of particles of matter?
The two processes that provide evidence for the motion of particles of matter are diffusion, where particles move from areas of high concentration to areas of low concentration, and Brownian motion, where particles in a fluid medium exhibit random movement due to collisions with surrounding molecules.
What evidence did J.J Thomson provided about this structure of an atom?
J.J. Thomson provided evidence about the structure of an atom through his discovery of the electron using cathode ray tubes. His experiments showed that electrons are negatively charged particles and are present in all atoms, leading to the development of the plum pudding model of the atom.

Why is indirect evidence important in studying the structure of the atom?
The atom is far too small to ever be examined directly. The diameter of a typical nucleus is only about 1/100,000 of the diameter of the entire atom and if an atom were magnified until it was as large as a football stadium, the nucleus would be about the size of a grape. Nearly all evidence of an atom's structure has been theorized.

Why do particles matter to forensic scientists?
Particles can provide valuable evidence in forensic investigations by linking suspects to crime scenes or victims. They can reveal information about a person's movements, activities, and contacts. Analysis of particles such as fibers, hairs, soil, and gunshot residue can help reconstruct events and identify potential sources of evidence.
What evidence is there of the particle theory?
The evidence for the particle theory of matter is supported by the behavior of particles in the kinetic molecular theory, such as the diffusion of gases, Brownian motion, and the interaction of particles in chemical reactions. Additionally, the observation of subatomic particles like protons, neutrons, and electrons further solidifies the particle nature of matter. Experimental data from particle accelerators also provide evidence for the existence of various elementary particles.

How do particles help in solving crime?
A criminal can leave behind evidence--hair, sperm, skin particles, that can link him/her to the crime.
