What is the particle model of matter?

Answer 1

Particles are always moving and there are 3 states of matter--gas, liquid, and solid.

^ that would be the Kinetic Molecular Theory (KMT).

-----

Hey. It's PIASM.

P- All matter is made up of tiny particles.

I- Subs are identical

A- All particles have attraction forces. This may have high or low.

S- There are space between Particles. And they always move.

M- Matter increases the space used.

This is Daltons' theory on matter. It's the key points.

^ Again, that would be the KMT.

*please read the explanation below.*

Particle Model and KMT are different.

Particle Model is self-explanatory; it does not describe the movement of particles, it just shows that:

1. all matter is made up of particles.

2. there are space between particles.

3. solid: particles are close together.

liquid: particles are further apart.

gas: particles are even more far apart.

But KMT also(#1 & 2 are also stated in the KMT, but #3 is a little diffferent.) describes the particles being in constant motion.

3. solid: particles are close, vibrating.

liquid: particles are further, and move faster.

gas: particles are even further apart, and move even faster.

Therefore, KMT and Particle Model are different.

Answer 2

the particle model of matter states:

1. All matter is made up of very small particles. The particles are much too small to observe with the naked eye or with a light microscope.

2. There are spaces between the particles. The amount of space between the particles is different for different states of matter. For example, gases have much more space between particles than solids do.

3. The particles are attracted to each other. The strength of the attraction depends on the type of material.

Extra Information:

Solid: Particles are packed together tightly. This means that a solid will hold a definite shape. They particles are constantly vibrating in place.

Liquid: Particles are in contract with each other, but can slip and slide past one anther. This means that a liquid takes shape of the container.

Gas:Particles have large spacing. Can move freely in all directions. Takes the shape of the container.

4. They are always moving and vibrating

Answer 3

The Particle Model of Matter is a scientific description of the tiny particles that make up all things. The key elements in this model are:

• All substances are made of tiny particles too small to be seen
• The particles are always in motion
• The particles have spaces between them

From what I have learned it tells you that all particles have spaces between them,

Answer 4

The entire universe is made of two things: matter and energy. For the time being we will concern ourselves with matter only.

I. Matter

Matter is defined as that which has mass and occupies space. This definition seems simple enough, yet there are profound issues which surround it. For example, there is currently no generally accepted scientific theory for why mass exists. It can be defined:

mass characterizes an object's resistance to a change in its motion.

But why it exists cannot yet be demonstrated. Mass just is, it just exists.

As we look into it more, definitions start to become circular, as in the definition of space:

space is that which is occupied by matter.

So, any definition of space exists only if there is matter. Take the matter away and space ceases to exist. Of course, saying "take the matter away" is very easy to say. It is quite another thing to specify what is meant by it.

As fun as these philosophical issues are, it's time to move on!!

II. Particles

All matter is particulate in nature. This basically means that between separate bits of matter there are spaces which contain no matter. In science it is called the "atomic nature of matter." It is generally agreed that the Greek philosopher Leucippus and his student Democritus were the first to propose this idea, about 440 B.C.. This "atomic theory" (to use a modern phrase) was opposed by Aristotle 100 years later, who taught that all space is filled with matter, that there are no empty spaces. Aristotle's ideas were accepted as correct by almost all educated people, until the early 1800's, when atomic ideas began to be more generally accepted as correct. There is a tutorial on this topic on this web site, titled The Greek Concept of Atomos: The Indivisible Atom.

Today, we know that there are many different particles which make up matter. Some are long-lasting, such as the proton. others are very, very short-lived, such as the top quark. The primary "particle" in chemistry is the atom. However, you probably know that there is a substructure to an atom; that it is made of protons, neutrons and electrons. You may also know that protons and neutrons are each made of three quarks. There are many other particles beyond the proton and neutron, some containing two quarks and some containing three.

There are two other categories of particles which appear to NOT be made of quarks: electrons and neutrinos. As far as science is currently able to tell, there are three types of particles with no substructure that we can detect: quarks, electrons and neutrinos. It may be that someday we will learn the the electron, for example, is made of still smaller pieces like an atom is made of protons, neutrons and electrons. That would be pretty cool!!

There is also a fairly sophisticated concept called "virtual particles." While it is based on some concepts you have not yet learned, it is still fairly easy to describe in a general way. There is energy also in the universe, we are just ignoring it for the time being in this tutorial. Some of the energy can spontaneously merge to form a particle of matter. (Einstein showed that matter and energy can be converted, one into another.) These "virtual particles" exist for very, very small amounts of time, so small that we cannot detect them before that pop back into being the energy they were made from. (These is another concept, called the Heisenberg Uncertainity Principle which affects the lifetime of virtual particles, but I will not go into here.)

Since the universe is flooded with energy, this means that, in every square centimeter of the universe, are trillions and trillions and trillions of virtual particles popping into existence every fraction of a second and then going back to energy. "Empty" space is actually a boiling cauldron of particles. Even though individual particles cannot be detected, the effect can. If you want to look into this farther, look up the "Casimir Effect" as well as learn what "polarizability of the vacuum" or "quantum fluctuation of the vacuum" means. It may be that Aristotle was right all along.

Answer 5

The particulate theory of matter states that matter is made up of very tiny particles that are in constant motion. It also states that the particles of matter are large compared to the particles themselves.

Answer 6

Interference.

Probably the deciding factor in abandoning the pure particle model would be the famous double-slit experiment (also known as Young's experiment). If you shine coherent light (eg a laser) on two parallel slits onto a screen, you get a pattern of light and dark bands called an interference pattern where some of the waves combine (bright bands) and some of the waves cancel each other out (dark bands).

It turns out that you can do the same thing with a stream of electrons - fire them at two slits and rather than, as expected, the electrons going through one slit or the other, they (like waves) go through both slits and interfere, giving the same interference pattern - even when only one electron is fired at a time! This proves that the electrons are not acting as particles, but as waves.
