As We Know Importance of NCERT Books For Any Board as well as Competitive Exams so you should Practice & Solve Each & every Question of NCERT. Try to Solve Each & Every Question given in NCERT Book so in this Article SciPhy is providing Nuclei NCERT Solution Of Chapter 13 Class 12 Physics. Total Weightage Of Dual Nature of Radiation & Matter and Atom, Nuclei is 12 . So to Score better each & every Mark is Important. Nuclei is an easiest Chapter so by less efforts you can Score Better.

How to Solve Numericals Or Other Numericals?

Firstly Read Statement of Question at least 2 Times & then try to understand what you have to find out from question & what values are given to you & How you can find out after that think about formula which you can apply here & Try to solve question your self & after solving check your answer if answer is correct that’s okey if not then check NCERT solution of Dual Nature of Matter & Radiation Provided by sciphy.

Avoid these Mistakes👇

• Never Use Calculator because at the present Moment it will save your time & During exam you will get only 3 hrs to solve paper at that time you will realise that your calculations is taking lots of time because in past you have used calculator & that will create Problem in future due to lack of practice.

Syllabus Of Nuclei 👇

PDF OF Nuclei Solution

Most Important Topics 👇

As this Chapter is not long so almost all topics are equally important & if we Compare among all Topics Binding Energy Per Nucleon & It’s Variation with Mass Number is important topic. Along with this Topic Nuclear Fission & Fusion is also Important.

Conceptual questions Related to Size of Nucleus & Nuclear Force is also important.

About Nuclei👇

•Composition Of Nucleus: Atom Consist of Central nucleus containing entire positive charge and almost entire mass. According to accepted Model nucleus is composed of Protons and Neutrons.

•Size of Nucleus:According to experimental Observations the Radius of Nucleus of an atom of Mass Number A is R = R₀A^1/3 . Where R₀= 1.2 fm.

• Atomic Masses :The Masses of atoms, Nuclei etc. are expressed in terms of atomic mass unit represented by amu Or ‘u ‘.

• Key Points:

• Mass of Proton (m_p) =1.007276u

•Mass of Neutron (m_n) = 1.008665u

•Mass of electron (m_e) =0.000549 u

• Isotope : Atom having same atomic Number(Z)but different Mass Number (A)

• Isobars : Atoms having Same Mass Number (A) but different Atomic Number (z)
