Bohr orbitals
WebApr 12, 2024 · Bohr's postulates include:-1. Electrons in an atom move in circular orbits around the nucleus, and their motion is quantized. 2. The energy of an electron in a particular orbit is fixed and does not change, and it increases as the distance of the orbit from the nucleus increases. 3. 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.
