    got keerthi...4s electron of copper screening constant =25.3 and Zeff=3.7

    eduncle-logo-app

    sir for calculating screening constant how u wrote 18 * 0.86

    eduncle-logo-app

    see keerthi n=4, n-1=3,n-2=2

    eduncle-logo-app

    check i have written which have what value of screening constant

    got keerthi??

    eduncle-logo-app

    no sir I'm not getting

    see keerthi as you have finding 4s value to 3rd period here have 18 electrons(3s2,3p6,3d10) and 2nd period and 1st period have 10 electrons

    eduncle-logo-app

    so keerthi 18×0.85+10×1

    eduncle-logo-app
