how did find the atom?

               All of student can`t learn well specially science like chemistry or physics or maths.Why?There is some problems in our learning way.We must not going to commit to memory when are we learning.We must understand what we learn.Then we can understand any difficult lesson easily.Also when we are going to learn chemistry we must understand what we learnt because chemistry is built by lot of assumptions.We can`t see atoms,molecular....like that.
              So we learn how did people find the atom?.How did people get some idea about a atom?.Now i`m going to tell you .How did people get some idea about a atom?

            There was more philosophers in our history.One of them of philosopher thought like this.We think a copper bar.He thought that what will happen is it divide for same two part.Then we can get same two part of copper bar.After we get one part of these two part.Now we divide for same two part again also.Then we can get another same two part also.After we get another one part and it also divide for same two part.we can repeat this procedure.But we can`t divide this copper bar anymore because it will very small part.This smallest part was very special part of chemistry.Concept of the atom is built from this part .Some of  philosophers debate about this smallest part.

• Some of them debated that "This part can be divided anymore" (element is continuous)
• Some of them  debated that " This part can`t be divided anymore" ( element is discontinuous)

What is the correct one?.Are elements (trees,animals,people,metals,water,air....) discontinuous or continuous?.what you think about this?.This was a big problem for philosophers.

         But we can`t see atoms in our naked eye.So we can`t accept there are atoms in elements.But philosophers say there is a atom in element.They also never see a atoms in their naked eye.So how can they say that there is a atom?.

         Once i said you that  Chemistry is built by some assumption.First we show some happen.After we do some experiment and then we can get some result.Then Scientists try to explain how to occur this happen using result.When scientist  

are going to explain about atoms,molecular ....they assume lot of assumption because atoms can`t see our naked eye.So first they assume some assumptions and they build some assumptions like atoms.But we can`t believe is it correct?.But we can explain lot of happens around chemistry using these assumption.So we have to accept these assumption as a correct one.

            So if we think there is a atom in elements we can explain lot of happen.So we have to accept that atom is a true.Also we know that there are electrons,protons,neutrons in a atom.But we can`t see it our naked eye.But if we think that there are electrons,protons,neutrons in a atom we can explain lot of happens in chemistry.

           We think about carbon atom.Scientists that says carbon atom has 6  electrons,protons,neutrons in one carbon atom .They decided there are  6  electrons,protons,neutrons in one carbon atom using some experiments` results.If we think that it has those e,p,n we can explain lot of happen in chemistry.
