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.
How are the particles of each state of matter arranged?
In solids, particles are tightly packed in a fixed arrangement. In liquids, particles are close together but can move past each other. In gases, particles are widely spaced and move freely.
What is the difference between the particles in a solid and the particles in a gas?
In a solid, particles are tightly packed together in a fixed arrangement, vibrating in place. In a gas, particles are widely spaced apart and move freely in random directions at high speeds.
State of matter containing most widely separated particles?
Gas is the state of matter that contains particles that are most widely separated compared to solid and liquid states. Gas particles are free to move independently and occupy the entire volume of the container they are in.
What are regions of air that have few particles?
Regions of air that have few particles are known as low-air-density areas. These regions can be found at high altitudes in the atmosphere, such as the stratosphere or thermosphere, where air particles are more widely spaced apart due to lower pressure. These areas are also associated with cleaner air quality and less pollution due to fewer particles being present.
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.

Who identified atoms had a positive nucleus with widely spaced electrons?
Rutherford is the one who experimented the internal structure of atoms by shooting alpha particles on a slim pieace of gold. he realised that most of Alpha particles gets through it, some of them deviates and the few rest bounce back. He concluded that the atom is consisted from empty space, and in its center lies a neculeus that resuls in bouncing back some of the particles and that this nucleus is positive to explain the deviation.
What evidence is there that the nucleus of an atom is very small and positively charged?
Rutherford's famous gold foil and proton experiment showed that very occasionally a proton fired at a nucleus came straight back at the 'gun'. He likened it to a naval shell being returned after hitting a piece of tissue paper. The fact that so few protons returned or were deflected by the tiny nucleus compared to the billions emitted by the proton 'alpha' source showed that nuclei of gold atoms were small and very widely spaced apart.
What is an area of crowded particles followed by widely spaced particles?
An area of crowded particles followed by widely spaced particles is known as a density wave. In a density wave, particles are closely packed together in one region, creating a dense area, and then spread out and become less concentrated in another region, resulting in a sparse area. This pattern repeats periodically, forming a wave-like structure.

How are the particles in each state of matter different?
In solids, particles are tightly packed, vibrating in fixed positions. In liquids, particles are more spread out and can move past each other. In gases, particles are widely separated and move freely in all directions.
Who is famous scientist and why is the famous?
well, there's Albert Einstein and he was famous for creating the atom bomb and plenty of other things. And Earnest Rutherford Rutherford performed his most famous work after he received the nobel prize for chemistry. In 1911, he postulated that atoms have their positive charge concentrated in a very small nucleus, and thereby pioneered the Rutherford model, or planetary, model of the atom. He is widely credited with first splitting the atom in 1917.
Name the state of matter in which the space between constituent particles is maximum?
Gas phase. In the gas phase, the particles are widely spaced apart compared to the solid and liquid phases, allowing them to move relatively freely and independently.
What describes the properties of solids liquids and gases in terms of the motion of particles?
Solid - Particles vibrate and rotate about a fixed position and do not diffuse measurably Liquid - Particles move freely in all directions slowly and diffuse slowly Gas - Particles move freely in all directions rapidly and diffuse rapidly
