Answer:
Dysprosium [Dy]=[tex][Xe]4f^{10}6s^2[/tex]
Americium [Am]=[tex][Rn]5f^77s^2[/tex]
Dysprosium is a chemical element with symbol Dy and atomic number of 66. It is a rare earth metal and as it contains partially filled f sub shells, it belongs to f block. Xe is the nearest noble gas and has atomic number of 54.
Americium is a chemical element with symbol Am and atomic number of 95. It is a rare earth metal and as it contains half filled f sub shells, it belongs to f block. Radon is the nearest noble gas and has atomic number of 86.
