explain the origin of the term atom?

Question

this is a hw question and that is all there was i will give 10 points to any1 that can also answer the following
1.describe brownian motion
2.describe the greek model of the atom
3. and the explain the orgin of the term atom

Answer 1

1. brownian motion is the random motion of particles within a fluid (such as air, water, etc)

3: Democritus, a Greek scientist/philosopher, coined the term atomos (plural atoma), meaning "cannot break down further" and "uncuttable."

2: The atom was the basic building blocks of everything in the universe. Everything that was visible was made from atoms, and there were different shapes for different atoms, hence the many shapes in the world. Atoms were indestructable and always moving.

Greek model of the atom: There were five kinds of atoms: earth, fire, wind, water, and "ether." Ether was everything that was created above the Earth's atmosphere. Ether did not have any distinct shape and was "pure and heavenly." The other four shared the same shape and were "flawed", but held different properties, derived in a bizarre way, but I guess appropriate for the time:
* Fire is both hot and dry
* Earth is both cold and dry
* Air is both hot and wet
* Water is both cold and wet
Fire would be able to burn Earth (hence wood used for fire) and Air is always above Water, and etc, etc. Everything on Earth was made from these 4 elements in different combinations, and so everything had different property variations.

Hope this helps.

Answer 2

Origin Of The Word Atom

Answer 3

Some scientist named Brown was looking at like pollen grains in water or something and notices the grains were not stationary but were moving around in jittery motions. Later when the Atomic nature of things became better understood, I think it was Einstein in conjunction with someone else who realised that the molecules of water are not stationary because of the energy in liquid water. Heat in anything causes its molecules to move around a bit. The pollen particles were being bumped by the liquid water molecules. The motion of particles caused by a liquid's kinetic energy is now referred to as Brownian motion.

Atom I have read is from Greek atomos meaning indivisible or unable to be cut or "uncuttable" or whatever. The ancient Greeks believed (like a prev answerer stated) that everything could be broken down into constituent particles up to a point when one arrived at the smallest particle of an element that retained that element's properties. Yes, they were wrong, but they did the best with the tech at hand i.e. not much. It wasn't until 19?? at the Cavendish laboratory at Cambridge University until atoms were first seen. Then in the early part of the 20th century the constituent parts of the atom were subsequently discovered--protons, electrons and neutrons. Now with modern accelerators, quarks have been discovered. Only with better tech can we ever see what a real "atom" is.

Answer 4

The word Atom is derived from the Greek language which means an entity that cannot be divided by natural means.
It really had nothing to do with the concept of what we call atom to day.
The greeks had different concept of matter at the micro level. however in the macrolevel they did make sense.
to day we have the same concepts except with different names;

solid state of matter
Gasous state of matter
Liquid state of matter
Plasma state of matter

This maches exactly with theGreek primitive version and description of matter.Except about the Aether we have the wrong idea . they had the right Idea.

Brownian Motion was discovered when it was observed in England that polen on the surface of water was moving eratically. But were unable to explain it. It was a Jewish- German genious by the Name of Einstein that explained the Phenomena at that time.
Note at that time Atomic theory was still on in its enfancy.
There were organizations which were completey set against the Idea that atoms existed. In the same way today there are organizations which are dead set against the Idea of the Aether.

Answer 5

In chemistry and physics, an atom (Greek άτομον meaning "indivisible") is the smallest possible particle of a chemical element that retains its chemical properties. The word atom originally meant the smallest possible indivisible particle, but after the term came to have a specific meaning in science, atoms were found to be divisible and composed of smaller subatomic particles.

Answer 6

an atom is the smallest particle of all but it consists of 3 other things
in an atom, there are electrons, neutrons, and protons that work in an atom to make it work

Answer 7

comes from the auto (french) meaning by itself then changed to atrom (greek) meaning very small, not seen.
don't believe a word i just typed cuz it is not right at all. i just wanted to mess with ya. thanks for the 2 points. (ha ha) :-)

Answer 8

Atom From Greek. atomos "uncut," from a- "not" + tomos "a cutting," from temnein "to cut."
