Maxwell’s equations in electromagnetism laid the groundwork for understanding the relationship between light and electromagnetic waves, contributing to the wave-particle duality concept. Sommerfeld extended Bohr’s model by introducing elliptical orbits and incorporating the concept of azimuthal quantum numbers, refining the description of electron behavior. Pauling’s work on the nature of chemical bonds, including the concept of hybridization, significantly advanced our understanding of molecular structure. See also 10 Importance of Sewing As a Skill Lewis introduced the concept of electron pairs and is renowned for his Lewis dot structures, which provide a simple method for understanding the bonding in molecules. This idea was foundational in the development of quantum theory. Planck introduced the concept of quantization of energy, stating that energy is emitted or absorbed in discrete units called quanta. This concept suggested that particles could display both wave-like and particle-like characteristics. His work, along with Heisenberg’s, contributed to the establishment of quantum mechanics.ĭe Broglie proposed that particles, including electrons, exhibit wave-particle duality. Schrödinger developed wave mechanics, providing a mathematical description of the behavior of electrons as waves. This principle laid the groundwork for quantum mechanics. Heisenberg formulated the uncertainty principle, emphasizing the limits of precision in measuring both the position and momentum of particles. His model explained the spectral lines of hydrogen, and it marked a crucial step towards the development of quantum mechanics. He proposed a nuclear model where electrons orbit a central, positively charged nucleus, drastically altering the understanding of atomic structure.īohr expanded on Rutherford’s work by introducing quantized energy levels for electrons. Rutherford’s gold foil experiment led to the discovery of the atomic nucleus. He proposed the “plum pudding” model, suggesting electrons were embedded in a positively charged matrix. Using cathode ray experiments, Thomson discovered the electron, a subatomic particle with a negative charge. His postulates became the cornerstone for later atomic models. Often hailed as the father of atomic theory, Dalton proposed that matter is composed of indivisible atoms with unique masses. Although his atomic concept lacked empirical evidence, it laid the foundation for future scientific inquiries.
