The 5 atomic models are: 1) Dalton's Model - atoms are indivisible units, 2) Thomson's Model - atoms have electrons in a 'plum pudding', 3) Rutherford's Model - atoms have a dense nucleus, 4) Bohr's Model - electrons orbit the nucleus in fixed paths, 5) Quantum Mechanical Model - electrons occupy orbitals based on probability. Understanding these models helps grasp atomic structure and behavior.
FAQs & Answers
- What is Dalton's atomic model? Dalton's atomic model, proposed in the early 19th century, suggests that atoms are indivisible units that combine in fixed ratios to form compounds.
- How does Thomson's atomic model differ from Rutherford's? Thomson's atomic model, known as the 'plum pudding' model, describes atoms as a positively charged sphere with negatively charged electrons embedded within it, whereas Rutherford's model introduced the concept of a dense nucleus at the center of the atom.
- What is the significance of the Bohr model? The Bohr model suggests that electrons orbit the nucleus in fixed paths, which helps explain the quantized energy levels of electrons and the spectral lines observed in hydrogen.
- What does the Quantum Mechanical Model explain? The Quantum Mechanical Model describes electrons as existing in probabilistic orbitals instead of fixed paths, allowing for a more accurate representation of atomic structure and electron behavior.
