जे जे थॉमसन परमाणु मॉडल की व्याख्या कीजिए
Answers
Explanation:
In Thomson's model, the atom is composed of electrons surrounded by a soup of positive charge to balance the electrons' negative charges, like negatively charged “plums” surrounded by positively charged “pudding”. The 1904 Thomson model was disproved by Hans Geiger's and Ernest Marsden's 1909 gold foil experiment.

J. J. Thomson, who discovered the electron in 1897, proposed the plum pudding model of the atom in 1904 before the discovery of the atomic nucleus in order to include the electron in the atomic model. In Thomson’s model, the atom is composed of electrons (which Thomson still called “corpuscles,” though G. J. Stoney had proposed that atoms of electricity be called electrons in 1894) surrounded by a soup of positive charge to balance the electrons’ negative charges, like negatively charged “plums” surrounded by positively charged “pudding”. The electrons (as we know them today) were thought to be positioned throughout the atom in rotating rings. In this model the atom was also sometimes described to have a “cloud” of positive charge.

जे.जे.थॉमसन, जिन्होंने 1897 में इलेक्ट्रॉन की खोज की थी, ने परमाणु मॉडल में इलेक्ट्रॉन को शामिल करने के लिए परमाणु नाभिक की खोज से पहले 1904 में परमाणु के बेर हलवा मॉडल का प्रस्ताव रखा था। थॉमसन के मॉडल में, परमाणु इलेक्ट्रॉनों से बना होता है (जिसे थॉमसन अभी भी "कॉर्पसप्राड्स" कहते हैं, हालांकि जीजे स्टोनी ने प्रस्तावित किया था कि इलेक्ट्रॉनों के ऋणात्मक आवेशों को संतुलित करने के लिए सकारात्मक आवेश के सूप से घिरे विद्युत के परमाणुओं को इलेक्ट्रॉन कहा जाता है) सकारात्मक रूप से चार्ज किए गए "हलवा" से घिरे नकारात्मक रूप से लगाए गए "प्लम" इलेक्ट्रॉनों (जैसा कि हम आज उन्हें जानते हैं) को घूर्णन के छल्ले में परमाणु भर में तैनात माना जाता था। इस मॉडल में परमाणु को कभी-कभी सकारात्मक चार्ज के "क्लाउड" के रूप में वर्णित किया गया था।
