How to calculate the radius of atom
Web4 mei 2024 · The nuclear radius is the distance from the centre of the nucleus at which the density of nuclear material decreases to one-half of its maximum value at the centre. Nucleus has no definite boundary, but its radius is given by following relation: R = R o A 1/3 Where R o is constant for all nuclei and its value is 1.2 x 10 -15 m WebUsing an Excel spreadsheet we calculated the percent surface atoms as a function of particle radius as shown in Fig. 1. If carried out to the upper limit of a nanoparticle radius, 50 nm, the percent of surface atoms drops to ~ 2%. Fig. 1 dramatically shows the leveling off of the fraction of surface atoms as the radius increases. Fig. 1.
