Raji Heyrovska_Strctural Insights etc_1June2015

A basic insight into the atomic structures of elements of the Periodic Table are presented in terms of their covalent radii, Bohr radii, nuclear and electron radii and their relation to the Golden ratio. The detailed structures of the quasi crystal forming elements, aluminium and manganese have been chosen here as special examples. At the atomic level, their crystal parameters and bond lengths are shown in detail for the first time and related to the Bohr radii obtained from the first ionization potentials. It is hoped that this work will provide deeper insights into the understanding of the bonding and alloy formation of different materials and help in designing materials for their intended purpose.
