With known information about the bulk properties of germanium, an effort has been made to investigate the characteristics of germanium when it is in nanoscale size. The effective use of germanium and its compound in nanotechnology and other fields requires an intensive study of the thermo-elastic properties in nano scale. Effect of size and shape on the melting temperature, thermal expansivity, and bulk modulus has been studied for pure nano germanium. An attempt has been made to compute Young's modulus using two different formalisms. A comparative study of both the formalisms with experimental values is presented in this work. The comparative study for Young's modulus brings out the most suitable formalism for germanium nano crystal to calculate this modulus</em><strong>.</strong> https://www.ijnnonline.net/article_245843_f16e3bb3d8099d8cdf15fd6c831e019d.pdf
