J. J. Thomson’s Plum Pudding Model (1904) marked the first scientific attempt to describe the internal structure of the atom after the discovery of the electron. Although later refined, this model laid the groundwork for the evolution of atomic theory taught in chemistry today.

The discovery of the neutron by James Chadwick in 1932 was a milestone in atomic science. It resolved key questions about atomic mass, isotopes, and nuclear stability, completing the fundamental model of the atom taught in chemistry today. Clear scientific concepts build strong foundations—for students and educators alike. https://www.chemistrynotesinfo.com/p/9th-class.html?m=1 #ChemistryEducation #AtomicStructure #NCERT #ScienceLearning#🔬विज्ञान के प्रयोग🧬 #Chemistry Notes Info #science #chemistry #📰GK & करेंट अफेयर्स Students💡

A tiny particle that changed the entire understanding of matter… In 1897, a simple glass tube experiment revealed something extraordinary — the electron, the first sub-atomic particle ever discovered. This single discovery shattered the idea of indivisible atoms and opened the door to modern atomic theory, electronics, and chemistry as we know it today. If you’ve ever wondered how atoms really work, this is where the story begins. 👉 Save this for revision.
