Question

An Element E (atomic weight=100) having bcc structure has edge length 400pm. Calculate the density of E, no. of unit cells in 20g of E.

Answer 1

Explanation:

An element 'A' of atomic mass 100 having bcc structure has unit cell edge of 400 pm. Calculate the density of 'A' and the number of unit cells for 10 g of 'A'. 'Stability of a crystal is reflected in the magnitude of its melting points. ... And hence, a substance with higher melting point would be more stable
