WebIonic solids are composed of cations and anions held together by electrostatic forces. Due to the strength of these interactions, ionic solids tend to be hard, brittle and have high melting points. Ionic solids are poor conductors of electricity except when their ions are mobile, such as when a solid is melted or dissolved in solution. WebIn a solid AB having NaCl structure, 'A' atoms occupy the corners of the cubic unit cell.If all the face-centered atoms along one of the axes are removed, then the resultant stoichiometry of the solid is : A AB 2 B A 2B C A 4B 3 D A 3B 4 Medium Solution Verified by Toppr Correct option is D) According to the structure of NaCl

WebFigure 10.37 The entities of a solid phase may be arranged in a regular, repeating pattern (crystalline solids) or randomly (amorphous). Metals and ionic compounds typically form ordered, crystalline solids. Substances that consist of large molecules, or a mixture of molecules whose movements are more restricted, often form amorphous solids.

WebIn the structure of NaCl each Na + ion is surrounded by six chloride ions. The following figure shows how these ions are arranged in the crystal lattice. It is clear that Na + ion has ten electrons while Cl – has 18 electrons. The size of the Cl – is bigger than Na +. The distance between two adjacent ions of the same kind i.e. Cl – ions ... http://chemed.chem.purdue.edu/genchem/topicreview/bp/ch13/unitcell.php WebThe structure of a crystalline solid, whether a metal or not, is best described by considering its simplest repeating unit, which is referred to as its unit cell. The unit cell consists of lattice points that represent the locations of atoms or ions. can i return my hertz rental car after hours
