Notes

Hello everyone I will come you all in this new chapter of chemistry again about matter in the Play is matter around us pure why we are discussing matter here just going to deal with matter in about the consequence of matter these can be atoms can be molecules on the ions also considered about two constituent of matter in this present chapter how do we measure release constituent how can we measure the matter also what are the units which I used to measure the matter how do we represent the concentration of matter so that is the whole contents of this presently so I just going to discuss about the introductory part of this chapter what's the name of the chapter here chapter is atoms and molecules also using the term atoms and the molecule as the name of the chapter the content of this particular click going to deal with the constituents of matter what was matter just recall matter is something that is present around you acid attack everything that you can observe around you that has mass that has volume is considered as matter who this matter is made up of chapter as well as effect talk about this lecture discuss about the different atomic theories analyse that there is atom inside matter in which will discuss about the laws of chemical combination also and then will describe a very important theory that was provided by John Dalton known as the atomic theory so let's begin this lecture with the very fast. That is you should always think why we are using the term atom for the smallest consequence definitely there should be some theory related to that number of even we should say the number of ancient philosophies number of Asian theories about ancient era water scientist even a lot of philosopher was there who analyse matter who discuss about matter even they said they told about the different substances which can be present inside matter as well as they also discuss about name that I can use your is more Harshita is terminal, philosophy if you look around that sucks all the matter is present around us method was termed as patatha by koshika if you divide that matter of Pratap University in the smaller constituency you will obtain the smallest constitution smallest constituent considered as smallest part of the market and name it as Parmanu use use the term whatsApp specie as per him this Parmanu is smallest constituent talk about the smallest constituent of metal the term that was was Burma right here that this is non divisible it cannot be divided for the if you cannot divided for the return the smallest constituent on all the matter consist of this Parmar about Maharshi gana every concept proposed by him was based on Simple philosophy and you might be knowing that if it's ok about something in Science that is space or experimentation prove by the experiment that matter is made up of Parmanu further to look at a certain other substance that is the constituent of smoke after that was another scientist who was he was also philosopher suppose that story on the basis of his philosophy that if we talked about matter by that matter into smaller and smaller pieces then we will obtain the smallest constituent and as per him the smaller constituent is first describe Atom was used by fellows of Democratic for their work with him on the Storm atom is derived from the Greek greek word is it review the word is greek word that is show me so disturb it Romeo is basically that something which is non divisible it cannot be divided further quite similar concept was proposed by moshika Nand as per him the substance is Parmanu that cannot be divided further in the similar manner democratic proposed the term atom that means I just want to right here the meaning of this term non Rishab sudarshan Mall Delhi sugar is derived from the Greek word on the basis of that it was assume that atom is the smallest constituent of matter but again the same thing is there that they try to was again the philosopher no experimentation was there no observation was there so how can we make a Theory on the basis of such philosophy this is not my thing email on the basis of experimentation and observation that science says after democratic they were the find this english school teacher who proposed the first atomic theory that is termed as deltas atomic theory who was the one was john Dalton english school teacher and he cried an atom as non divisible constituent of matter which cannot be further divided and that is the main constituent of all the matter atom is smallest constituent of matter churi named as planktons atomic theory discuss about this deltas atomic theory in the relative path of distract towards that part in which we are just going to discuss about the deltas atomic theory for the laws of chemical combination”
