True or false atom is the smallest unit of matter which substances can be divided without loosing its basic?

Answer 1

False -

now what are you going to do?

Answer 2

The atom is the basis of all Chemistry and most of the reactions that are important to humans.

At one time it was felt that there were three basic building blocks for all atoms, electrons, neutrons, and protons. These were considered by chemists to be the smallest pieces of matter. This continued to be preached by Chemists despite the fact that Sub-atomic particles had already been identified that were not neutrons, protons or electrons.

At one time it was also theorized by a famous scientist that the Electrons orbited around a nucleus made up of Protons and Neutrons much like a satellite orbits around the earth.

Physicists, starting with Albert Einstein have pretty well killed these early theories of the make up of matter and it is now recognized that both Protons and Neutrons are made up of sub-sub Atomic particles and that there may be some basic building blocks for Protons and Neutrons.

I guess what this points out is that we must adapt to improved theories as they develop and as they better explain the goings of the universe so while we can currently state that the atom is indeed the smallest unit of matter that has a basic, unchangeable property we may at some time find exceptions to that statement that required a more in depth understanding, and where the explanation might possibly involve some of the sub-sub atomic particles discovered by the Physicists.

Hang loose and be flexible is the best advice.

Answer 3

I think the way the question has been framed, the answer has to be false

whereas the atom is the smallest unit where a substance has its chemical properties, as this is the engineering area it is important to point out that it looses its *physical* properties well above this level.

take for example the way carbon can exist as graphite, diamond, buckyballs, nanotubes etc. This is dependent on the structures built from the atoms. Another good one is sulphur which has 3 distinct allotropes as I recall.

the whole stuff with nanotech is that if you get tiny chunks of stuff, they can actually behave very differently to the bulk substance. Hence some of the safety concerns - substance X may be fine when you make a brick of it, but dangerous if it is floating about in 10nm particles

Answer 4

True in the case of elements
and false for the substances as that particle is Molecule

Answer 5

An atom is the smallest part of a substance which is an element, and which contributes directly to that element's nuclear, physical and chemical properties. e.g. copper or gold.

Answer 6

theres protons neutrons inside atoms and quarks thats not a noise a posh duck makes but is a good word for scrabble

Answer 7

false, but when its divided its dependency on the equation of the substances are unknowing

Answer 8

What I believe you are asking is whether this is the smallest unit that will retain the property of that element. ie, gold. The answer is true.

Answer 9

True

it can be broken down into elemets

Answer 10

true
