Web30 jan. 2024 · In the Bohr model of the hydrogen atom, the radius of the electron orbit in state n is equal to n 2 a 0, where a 0 is the Bohr radius. The speed of the electron in state n is α c / n, where α is the fine structure constant. The energy of state n is equal to − R ∞ h c / n 2, where R ∞ is the Rydberg constant. WebThe lowest value of n is 1; this gives a smallest possible orbital radius of 0.0529 nm, known as the Bohr radius. Once an electron is in this lowest orbit, it can get no closer to the proton.
