    well the noble gasses has stable configurations so you can used the next lowest noble gas as your base,

    just remember a fully filled d orbital or half filled d orbital in this case makes it more stable

    dont ask why it did not fill up 18 first,that is beyond ur scope if ur in 9th,ull learn about it in class 11 when u learn about orbitals and shells.
