Topics NEET asks most

TopicQuestions
Nuclear size, mass defect and binding energy 56
Nuclear fission and fusion 40

NCERT lines NEET asked again and again

Read these lines from your NCERT book twice: NEET has built questions on each of them more than once.

Nuclear radius grows as R = R₀A^(1/3), so volume is proportional to A and the density is the same for every nucleus .
AIPMT 2008AIPMT 2015NEET 2022NEET 2026
Stability is judged by binding energy per nucleon . It rises, peaks near iron, then slowly falls for heavy nuclei, which is why they can split.
AIPMT 2005NEET 2013NEET 2021
Fusing nuclei must overcome their Coulomb repulsion , so fusion needs very high temperature. The Sun's energy comes from such fusion of hydrogen.
AIPMT 2003AIPMT 2011AIPMT 2011
Slow (thermal) neutrons split ²³⁵U most easily. Water works as a reactor coolant because of its high specific heat capacity .
