covalent crystal मीनिंग इन हिंदी

Crystalline solids generally consist of an ordered array of interconnected atoms, generated by repetition of a unit cell in three dimensions, and are of two extreme types ionic crystals, and covalent crystals.
Ionic crystals are made up of quite different ions, such as Na + and Cl " in common salt, for example, while covalent crystals such as diamond are made up of atoms that share electrons in a covalent bond.
