WebSolution: We will use the following diameter formula to find the diameter of the circle. Diameter = 2 × Radius. D = 2 × 24 = 48 inches. Answer: The diameter of the given circle = 48 inches. Example 2: Find the diameter … WebAtomic Radius. Unlike a ball, an atom does not have a fixed radius. The radius of an atom can only be found by measuring the distance between the nuclei of two touching atoms, and then halving that distance. As you can see from the diagrams, the same atom could be found to have a different radius depending on what was around it.

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. The Bohr radius (a0) is a physical constant, approximately equal to the most probable distance between the nucleus and the electron in a hydrogen atom in its ground state. It is named after Niels Bohr, due to its role in the Bohr model of an atom. Its value is 5.29177210903(80)×10 m.
