Calculate the radius of copper atom if it crystallise in face centred cubic lattice and has a density of 8.93 g / cm cube. Solution Structure given = fcc For fcc , Z = 4 Density , d = 8.93 Molar mass , M = 63.55 Avogadro number = 6.2×10^23 Use the given formula InContinue reading “Calculation of edge length and radius of atom.”

Why does a covalent bond not form a crystal lattice?
Covalent bond and ionic bond has a very basic difference that is presence of ions or not. The ionic bonds are not limited to one ion only, actually they keep on joining again and again because they are held together by basically the electrostatic forces, due to the oppositely charged ions. lets take example ofContinue reading “Why does a covalent bond not form a crystal lattice?”
