Atomic models explain how scientists understand the structure of the atom. Over time, these models improved as new experiments were performed. Here’s a clear, step-by-step overview: 1. Dalton’s Atomic Model (1803) Scientist: John Dalton Main Ideas: Atom is a solid, indivisible sphere All atoms of an element are identical Atoms combine in fixed ratios Limitation: Could not explain subatomic particles (electron, proton, neutron) 2. Thomson’s Atomic Model (1897) Scientist: J. J. Thomson Main Ideas: Atom is a positively charged sphere Electrons are embedded like raisins in pudding Limitation: Failed to explain atomic nucleus 3. Rutherford’s Atomic Model (1911) Scientist: Ernest Rutherford Main Ideas: Atom has a small dense nucleus Electrons revolve around nucleus Most of the atom is empty space Experiment: Gold Foil Experiment Limitation: Could not explain why electrons don’t fall into nucleus 4. Bohr’s Atomic Model (1913) Scientist: Niels Bohr Main Ideas: Electrons move in fixed orbits (energy levels) Energy is quantized Electrons jump between levels by absorbing/emitting energy Limitation: Works well only for hydrogen atom 5. Quantum Mechanical Model (Modern Model) Scientists: Erwin Schrödinger, Werner Heisenberg Main Ideas: Electrons exist in probability clouds (orbitals) Exact position cannot be known (uncertainty principle) Uses mathematics and wave functions Best Model: Explains all atoms, bonding, and spectra #FScPhysics #physicsnotes #physicsvibespk #atomicmodel #modernphysics

ATOMIC MODEL THROUGH HISTORY 1. John Dalton’s Model (1803) – Solid Sphere Model Overview: Dalton proposed that all matter is made up of indivisible particles called atoms. He imagined atoms as tiny, solid spheres—like billiard balls. Key Ideas: Atoms of the same element are identical in mass and properties. Atoms cannot be created, divided, or destroyed. Compounds form when atoms of different elements combine in fixed ratios. Importance: First scientific model of the atom based on experimental evidence (like gas laws). Laid the groundwork for modern chemistry. --- 2. J.J. Thomson’s Model (1904) – Plum Pudding Model Overview: After discovering the electron, Thomson proposed that atoms are made of a positively charged substance with negatively charged electrons scattered within it—like raisins in pudding. Key Ideas: Atoms are divisible. Electrons are negatively charged subatomic particles. The rest of the atom is a blob of positive charge to balance the electrons. Importance: First model to show that atoms have internal structure. Introduced the idea of subatomic particles. --- 3. Ernest Rutherford’s Model (1911) – Nuclear Model Overview: Conducted the gold foil experiment where alpha particles were fired at a thin sheet of gold. Most passed through, but some were deflected at large angles. Key Ideas: Atoms are mostly empty space. A small, dense, positively charged nucleus is at the center. Electrons orbit around this nucleus. Importance: Disproved the plum pudding model. Introduced the concept of a nucleus. --- 4. Niels Bohr’s Model (1913) – Planetary Model Overview: Bohr expanded on Rutherford’s model using discoveries from quantum theory. Key Ideas: Electrons orbit the nucleus in fixed paths or “energy levels.” Each level has a specific amount of energy. Electrons can jump to higher levels when energy is absorbed and fall back down when energy is released (as light). Importance: Explained why atoms emit light in specific colors (atomic spectra). Added the concept of quantized energy levels. --- 5. Erwin Schrödinger’s Model (1926) – Quantum Mechanical Model (Electron Cloud Model) Overview: Schrödinger used complex

✨️What does an atom look like?✨️ ⬇️⬇️ Did you know? The structure of the atom, according to Bohr's model and other early 20th-century models, can be described in physical terms quite simply: Atomic Nucleus: At the center of the atom is the nucleus, composed of protons (positively charged particles) and neutrons (neutral particles). This nucleus contains most of the atom's mass. Electrons: Electrons are negatively charged particles that orbit the nucleus in specific layers or energy levels. In Bohr's model, these levels are well-defined, and electrons can move between levels by absorbing or emitting energy in the form of photons. Quantum Models: Following Bohr's model, more advanced models incorporating quantum mechanics principles were developed. Let's start discussing atomic orbitals, wave functions, eigenstates, Hilbert space, Heisenberg's uncertainty principle, radial distribution functions, etc. Etc. All of these were introduced following Bohr's atomic model and Scattering Rutherford . These models treat the positions of electrons not as precise orbits but as "probability clouds" that indicate where an electron is most likely to be found at any given time. These initial physical models of the atom laid the groundwork for modern understanding of atomic structure, which continues to evolve with further research and technological developments. ✨️✨️✨️ 🌐Music: Gangsta - Nobody knows (Remixed) 🌐Clips used in this uploaded editing:Atomic Orbitals animation credit: Sci Pills ( YouTube channel) ☆•☆•☆ ☆▪︎☆▪︎☆ 🌐CREDIT COMPOSITION/FORMATTING/ EDITING/FURTHER PROCESSING @glamour_physics @modernsciencex CONTENT USED FOR EDUCATIONAL PURPOSES ONLY ☆•☆•☆ For more insightful content on Science and Astronomy 🌐FOLLOW @glamour_physics ☆▪︎☆▪︎☆ For the pics/clips used in this uploaded editing: All Rights And Credits Reserved To Respected Owner (s) No copyright infringement intended .

J. J. Thomson proposed one of the earliest atomic models in 1904, commonly known as the Plum Pudding Model. 🔬 Key Ideas of Thomson’s Model The atom is a uniform sphere of positive charge. Electrons (negative charges) are embedded inside this sphere. These electrons are scattered throughout, like plums (dry fruits) in a pudding 🍮. The total positive charge balances the negative charge of electrons, so the atom is electrically neutral. 🧠 Simple Understanding Imagine a soft ball of positive charge, and tiny negatively charged electrons are stuck inside it. 📌 Features Explained the presence of electrons in an atom. Helped in understanding that atoms are divisible (not indivisible as earlier thought). ❌ Limitations Could not explain atomic stability. Failed to explain results of the Rutherford Gold Foil Experiment, which later led to a new atomic model. #ThomsonmodelofAtomclass9thand11th #chemistrynotes #Chemistryconcept
