2 min readFeb 7, 2022

Atoms, One of the easiest chapters and mostly theoretical. This is the one thing that you have been reading since 8th std, where you just had an idea of a fundamental unit called atom. Well, now you’re gonna read more about it, how it was discovered and everything related to it.

And to make things a little easier for you, Doubtconnect provides you the required resources, tips, and tricks that you need to ace this chapter.

So here you go!

So before we get into the chapter, let’s see what we’re gonna deal with inside this chapter.

  • Introduction
  • Alpha Particle Scattering
  • Rutherford’s Nuclear Model of Atom
  • Atomic Spectra
  • Spectral Series
  • Bohr’s model
  • The line spectra of the hydrogen atom
  • De Broglie’s explanation

Short Notes

(we don’t claim this, it was available on the internet)

Well, It’s just for your benefit.

So Now let’s see how we’re gonna go through it.

At first, you need to go through concepts, concepts will be developed after watching a good amount of animated content or any content related to it.

So here are a few video suggestions. We’ll cover both free and the paid content, here’s the list.

  • Atoms, Sachin Sir Physics, Youtube (Free)
  • Vedantu Youtube (Free)
  • Apni Kaksha,Youtube (Free)
  • Atoms by Physics Wallah (Free + Paid)
  • Atoms by Unacademy (Free + Paid)
  • NV Sir, Atoms, Etoos (Paid)


Well, there’s nothing much to worry about books when it comes to Atoms.
You can just revise your NCERT throughout and nothing will come apart from that.

All the theory and numericals that you need are all available in NCERT Class 12th Physics.


Now is the time to revise and start answering practice questions. But we need to remember that practice questions will not give us an actual hang of the examination. So just be prepared for it by revising your notes again and again.

And one very important suggestion is that you should prepare SHORT NOTES, especially for this chapter. You can refer to the short notes that we have attached to the blog.

So this is all that you need to conquer this chapter as nothing more is required. Atoms, Done and Dusted once you’re done doing all the things mentioned above.

Also, if you face any doubts regarding your subjects, Physics, Chemistry or Mathematics, we’re there for you ;)
