    sir ye shortest distance me 2Na kyun lia gya hai..

    eduncle-logo-app

    ye Nacl ka structure hai or black dot represents Na atom and white dot represent cl atom

    eduncle-logo-app

    so in fcc nearest distance between two atom is a/root 2

    eduncle-logo-app

    2 Na+ ions ke beech shortest distance dekho image se...ye a/ root 2 hota hai

    eduncle-logo-app

    sir phir ye last me square root kyun lia gya hai??

    eduncle-logo-app

    distance between Na+ ions = root 2* a/ 2 ho jayega ...to last me directly a/root 2 bach jayega
