Radius of hydrogen

WebThe hydrogen anion, with its loosely held two-electron cloud, has a larger radius than the neutral atom, which in turn is much larger than the bare proton of the cation. WebMar 18, 2024 · The hydrogen atom has only certain allowable radii and these radii can be predicted from the equation that relates them with each \(n\). Note that the electron must be in motion so \(n = 0\) is not allowed. This plot shows the relationship of Radius as a function of \(n\). Note that at \(n=1\) the radius is not zero.
