Schrödinger’s Model (Quantum Mechanical Model) 6. Electron Cloud Model 7. Quark Model. Understanding these models reveals the evolving nature of atomic theory.
FAQs & Answers
- What is Dalton's Atomic Model? Dalton's Atomic Model, also known as the Solid Sphere Model, suggests that all matter is composed of indivisible atoms that are identical in mass and properties.
- How does Thomson's Model differ from Dalton's? Thomson's Model, known as the Plum Pudding Model, proposes that atoms are made of a positive 'pudding' with negatively charged electrons embedded within, contrasting with Dalton's indivisible atom concept.
- What is the significance of Rutherford's Nuclear Model? Rutherford's Nuclear Model introduced the concept of a dense and positively charged nucleus at the center of the atom, leading to a better understanding of atomic structure compared to previous models.
- What is the Electron Cloud Model? The Electron Cloud Model suggests that electrons exist in probabilistic cloud-like regions rather than fixed orbits, emphasizing the uncertainty in an electron's position.
