The smallest particles of chemistry, the atoms of the elements, which hitherto had been approached merely by inductive thought, now became tangible realities, so to speak, which could be counted and whose tracks could be photographed. A series of remarkable experimental investigations, stimulated largely by the English physicist, J. J. Thomson, had disclosed the existence of negatively charged particles, the so-called electrons, ⁴\/₂₀₀₀ the mass of the smallest atom of the known elements.","brand":"DD Sales","offers":[{"title":"Default Title","offer_id":53572759027991,"sku":"9789372305111","price":428.4,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6918\/8119\/files\/3528414.webp?v=1782375026","url":"https:\/\/payment.letskitaboo.com\/ur\/products\/the-atom-and-the-bohr-theory-of-its-structure","provider":"Kitaboo One eStore","version":"1.0","type":"link"}
