Neco 2018 Chemistry Question 37
Practice objective / multiple choice question 37 from the 2018 Neco Chemistry examination.
An element X forms a metallic solid that crystallises in a body‑centered cubic (BCC) lattice. The solid has a density of \(8.96\ \text{g cm}^{-3}\) and an atomic mass of \(63.5\ \text{g mol}^{-1}\). (a) Determine the number of atoms per unit cell for the BCC structure. (b) Calculate the edge length \(a\) of the unit cell in picometres. (c) Using the geometric relationship for BCC, find the atomic radius \(r\) in picometres.
