It is the number of lattice points touching one lattice point in a crystalline solid. For example in case of Sodium chloride it is 6 .

Explanation of Schottky defect, Frankel defect, Interstitial defect and F-centres.
1. Schottky defect:- In this kind of defect equal number of cations and anions are missing from the crystal lattice. Due to this the vacant sites or the holes are present in the lattice. This kind of defect is present in the ionic compounds with high coordination number and equal size of ions. Density ofContinue reading “Explanation of Schottky defect, Frankel defect, Interstitial defect and F-centres.”
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?”
What causes Ionic bonds to form? Use NaCl (table salt) as an example to explain the formation of ionic bonds.
it is a very common question and common example too. i would love to answer. Most people say it is the bond formed due to the transfer of electrons, but this explanstion is not complete. Ionic bond is the bond formed due to strong electrostatic forces of attraction between two oppositely charged ions. here isContinue reading “What causes Ionic bonds to form?
