WebA shortcoming of the Bohr model was that it could only predict the atomic spectra of hydrogen. It in essence treated an electron as a classical object in an orbit around the nucleus, where in reality an electron is a quantum particle that has wave-particle duality. WebSep 12, 2024 · The physical explanation for the first Bohr quantization condition comes naturally when we assume that an electron in a hydrogen atom behaves not like a particle but like a wave. To see it clearly, imagine a stretched guitar string that is clamped at both ends and vibrates in one of its normal modes. ウェーダーおすすめ磯

Wave–particle duality is the concept in quantum mechanics that every particle or quantum entity may be described as either a particle or a wave. It expresses the inability of the classical concepts "particle" or "wave" to fully describe the behaviour of quantum-scale objects.

WebSep 12, 2024 · The electron’s speed is largest in the first Bohr orbit, for n = 1, which is the orbit closest to the nucleus. The radius of the first Bohr orbit is called the Bohr radius of hydrogen, denoted as a0. Its value is obtained by setting n = 1 in Equation 6.5.6: a0 = 4πϵ0 ℏ2 mee2 = 5.29 × 10 − 11m = 0.529 Å.
