WebThe solid region is rotation about y-axis at x=6. So we will have a washer shape and inner radius of shell is r and outer radius is R. In this example, we will find the inner radius by the distance between the line x = 4 and the line x = 6, so r = 2. The outer radius R is the horizontal distance between the graph of y=√x and the line x = 6.

Webwhich is identical to the Rydberg equation in which R ∞ = k h c. R ∞ = k h c. When Bohr calculated his theoretical value for the Rydberg constant, R ∞, R ∞, and compared it with the experimentally accepted value, he got excellent agreement. Since the Rydberg constant was one of the most precisely measured constants at that time, this level of agreement was … WebNov 21, 2024 · Atomic Radius of Helium. The atomic radius of Helium atom is 28pm (covalent radius). It must be noted, atoms lack a well-defined outer boundary. The atomic radius of a chemical element is a measure of the distance out to which the electron cloud extends from the nucleus. However, this assumes the atom to exhibit a spherical shape, …
