Whatever do you mean? There are no specks of dust smaller than an atom. Now since you say they talk about the "weight of an atom" did they think there was only one atom? Different atoms have different weights. Did they have one particular atom in mind and what did they call the different atoms?You said that "the word used in the verse is tharratin which simply means an object smaller than an atom". That means that "tharratin" is arabic for electrons, protons and neutrons and elementary particles. Is it a common name for all of them or did they mean one specific? Since they knew about them what did they call them individually?

Firstly.
We await your findings on weather At-Tabari,Al Qurtubi,Al-Baydawi, and Az-Zamakhshari tafsir was mentioned on the
Al Tafsir.com - Tafseer Holy Quran from all Tafseer Schools, Quran Translations, Quran Recitations, Quran Interpretation (Tafseer), Quran Sciences, and Love In Quran site.
Secondly.
Please make the following stick into your brains and make sure its airtight.
Whenever the Noble Quraan is translated,in what ever launguage,it no more becomes the word of God Almighty.The translated Noble Quraan hence becomes the words of the translater of the Quraan.That is why you will never get 2 English translated Quraans being in exactly the same word for word.Each translated Quraan is basically the views and opinion of the translator and hence it becomes the word of man and that is exactly why you will find blatant inaccuracies and errors.Therefore translated Quraan are simply meaning of the
Quraan and not the actual Glorious Quraan itself.
Thirdly.
Before answering your question to alleviate your ignorancy let me give you a small lesson on the Glorious Noble Quraan.
In the Glorious Noble Quraan there are 2 types of knowledge that we learn of.
1.llm bil Hadhir which simply means knowledge of something which is present to us right here and right now.
2.Ilm bil Ghayb which simply means knowledge of something which we know but is not here now.
Also llm bil Ghayb refers to knowledge that is concealed from us humans.In other words we know the object is there but we will never be able to discover it.
Note this is a very lengthy subject and i am not going to go into it in detail because its a subject on its own.
Now to answer your question.
The arabic word "tharratin" which refers to an object falls under the knowledge of llm bil Ghayb.We,as humans,know what the object is, that is a speck of dust,but we have not as yet discovered it nor will we ever discover it because it is concealed.
So far as your question that there are no specks of dust smaller than an atom actually shows how ignorant you are on the knowledge of atoms.
What is dust?
It is a component of particulate matter.
What is an atom?
Is is a unit that makes up all matter.
What does an atom composed of?
protons,neutrons,electrons
What does an protons and neutrons composed of?
quarks.
What does a quark composed of?
Well this knowledge is beyond man at this present time.But definately when he upgrades his tools he is going to find a new discovery and if he calls this discovery A then definately A will also be composed of a particle and when he makes this discovery then he will call it B and B will also be composed of a particle.Simply put it his discoverys will take him to infinity.
This infinity is what we call llm bil Ghayb.The object that God calls "tharratin" is concealed.
Your question on weight of an atom again shows complete ignorancy. Atoms range from 0.1 to 0.5 nanometers in width.One nanometer is around 100,000 times smaller than the width of a human hair.
Now if "tharratin" is the infinite divisibility of an atom then i leave you to do the mathematical calculation of the weight of the arabic word "tharratin".
Note "tharratin" is
definately not arabic for electrons, protons and neutrons and elementary particles that you are claiming.
Hope that i have answered all your questions.
