Abstract:
A basic insight into the atomic structures of some important alloy forming elements, like magnesium, aluminum, titanium, niobium etc will be presented in terms of their covalent radii, Bohr radii, nuclear and electron radii and their relation to the Golden ratio, using the data provided earlier for the elements of the Periodic Table. It is interesting to point out that for the elements of Group A: Rb (1.72, 2.79), Cs (1.85, 3.02), Mg (0.94, 1.60), Ca (1.18, 1.98), Sr (1.26, 2.15), Al (1.20, 2.02), P (0.69, 1.11), As (0.74, 1.25), He (0.29, 0.46) and Group B: Pd (0.86, 1.38), where the 1st and 2nd terms in the parenthesis are their Bohr radii, a(B) (from 1st ionization potentials) and covalent radii R(cov) in A…, respectively, the ratio, R(cov)/a(B) is close to the Golden ratio (1.62). These and other relations, it is hoped, will provide deeper insights into the understanding of the bonding and alloy formation of different materials and help in designing materials depending on their intended purpose.
