Diameter of a ground-state hydrogen atom
WebFind the probability per unit length of finding an electron in the ground state of hydrogen a distance r from the nucleus. At what value of r does this probability have its maximum value? Solution: Given the ground state wave function ψ 100 (r,θ,φ) = ψ 100 (r) = [1/(π 1/2 a 0 3/2)]exp(-r/a 0), we find the probability per unit length, WebPractice entering numbers that include a power of 10 by entering the diameter of a hydrogen atom in its ground state, dH=1.06×10−10m, into the answer box.

WebSep 9, 2024 · The electron in the hydrogen atom posses an electrostatic force which gives a centripetal force. ----- (2) replacing the value of v in equation (1) into (2), and taking r as the subject of the formula, we have: For ground-state n = 1. Therefore, the diameter of hydrogen d = 2r 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.
