I study in RUclips all Chanel but your teaching experience is different from other chemistry teacher thanks sir very very very thanks 🙏🙏🙏🙏🙏
Sir you are best teacher of chemistry subject
Thank you so much for your kind words! I'm so glad that our videos have been helpful for you!
Yes 😂 best teacher for chemistry
Very very very nice 🎉
thanku sirr so much for making the concepts crystal clear. thanku so much
Hello sir your teaching methods are amazing 😊😊
Sir your teaching method is just awesome 👌
U are best teacher on u tube then other foundations ,they also have knowledge but they don't know how to teach average students but u sir amazing
Thank you so much for the compliments! We're really happy to hear that our videos are helping you out and that you enjoy them. Keep up the good work!
thanks sir for this amazing lecture 😊😊😊😊
sir law of conservation of mass states that mass can be nor be created or destroyed during chemical reaction but can be destroyed in some other cases

Mass no of sodium is 23
Atom of each element is an ultimate particle, and has a characteristic mass but is Structureless. This is the 3rd postulate of Dalton's atomic theory. Everything is clear but what is structure less mean here please clear and explain it . ❤
Yess i also have doubt for it that we can able to define atom's structure then why it is called structure less
Because unka structure bdl jata h jese c+02 ye structure me h Or jab = me co2 ayega to structure bdl jayega to ye structure less ho jayega may be you'll understand if yes then tell 😩👀
@@aim_neet3091 oh I tried but i didn't get it🥲
@@aim_neet3091 ohh!! Thanks ♥️
@@_monster__gaming_6960 make the structure of carbon and oxygen then make the structure of carbon dioxide see the difference.atoms have it's own structures but when it comes to compound the structure change because atom constantly take part in chemical reaction and change their electron configuration, if electronic configuration change so structure change then I can say a particular atom , molecule and compound is structure less....get it
isotopes are those elements which have same atomic number but different mass number.
Absolutely right
Correct bro
Guru dev hm apka krj kesse chukae ge
Apne to hme prm Gyan ki prapti krva di😂
34:14 those elements which have same atomic mass but different molecular mass
Sir please bring one shot revision lecture after completing one chapter.

Isotopes are atoms of the same element that have the same atomic number but different mass numbers.
Any atoms of an element having same atomic number but different atomic mass is called isotopes.
Thank you for your comment! We're glad you found our educational video on isotopes helpful. At TopperLearning, we offer a wide range of educational videos for school students across India. We hope you continue to watch and learn from our videos.
@@MagnetBrainsEducation Thank you Sir 🙏
Age of John Dalton is wrong in the textbook and in the ppt as well
His age is ( 1766 - 1844)
Magnet brain team specal thanks from me to You for this important + free video
35:04 sir isotopes vo hotey hai jinki atomic number same hoti hai pur unki atomic mass different hoti hai aur iskai examples hai c-12 , c-13 , c-14 atoms jinki atomic number tho same hai pur inki atomic mass different hai
Hi magnet brains team , I am neet aspirant 2026 please can you start new batch of combined Bio,Physics and Chemistry for 11th class following the new syllabus. BTW thanks for awesome lectures I am loving it ❤ 😊😊

Thanku sir
Sir aap bohot bohot achha padhate ho mein chemistry ke liye sirf Aaphi ki classes attend karti hu 🥰 you're brilliant sirrr and thank you so much
😂😂
Sir does atom theory comes from Kanaad rishi and pass onto Greeks??
Atoms is known as smallest particle of any substance which we can't divide. So atom is a smallest particle it mean it have any shape also. So why u explain that atom is structure less.
Sir if possible pls make lectures in serial wise topics according to book ... Sometimes they are not serial wise

Haa
ha bhaii baat to sahe hai
Haan
Sir ap bahot achhe s samjhate ho koi bhi topic ko
Sir I am confused that we can able to define atom's structure then why this is called to be as structureless .please resolve this doubt. 🙂
Dalton told that it is structureless 😅
@@jenijs8847 yess😅
The term "structureless" in the context of atoms is somewhat outdated and inaccurate. Historically, early models of the atom, like J.J. Thomson's "plum pudding" model, suggested that atoms were uniform, structureless spheres of positive charge with embedded electrons. However, as scientific understanding advanced, it became clear that atoms have a definite structure.
The modern understanding, based on quantum mechanics, describes atoms as having a nucleus composed of protons and neutrons, surrounded by electrons in specific energy levels or orbitals. This structure provides a more detailed and accurate depiction of the organization of subatomic particles within an atom. Therefore, the term "structureless" is not an accurate representation of the current understanding of atomic structure.

Sir you are teaching very good thnks sir
Sir please tell me how to calculate mass number?
Thank you for watching our educational videos! To calculate the mass number, you need to add the number of protons and neutrons in an atom.
@@MagnetBrainsEducation ok sir thanks for replying
The atom of an element having same atomic number but different mass number are called isotope
Sir element or atom me difference kia hai
Isotopes are the atoms of the same elements having same atomic no but different mass number.

Isotopes which have same atomic number but different atomic mass
Iso means "same" and topes means "forms" so different forms of an element are called it's isotopes ❤❤❤ am I right plzzz guide me sir🙏🙏🙏
Sir kya neet ka preparation alag se karna parta hai?
Yes, you need to prepare for NEET separately as the syllabus is vast and requires undivided attention. However, you can take help from our expert teachers who have designed NEET specific courses which will help you cover the syllabus efficiently.
