4f14 is the full orbital of elements from lanthanum to Ytterbium (14 elements). Lutetium is the first element in the 5d orbital.
Barium has the noble gas configuration [Xe]6s2. You can learn about noble gas configurations at.
No, 2s 1 electronic configuration is not possible for hydrogen . Energy of the orbital decide the filling of electron. Since lower energy orbital is always preferred for filling of electron than orbital with higher energy.
The names of the electron shell were given by a spectroscopist named Charles G Barkla. He named the innermost shell has k shell because he noticed that the X-rays emitted two types energies .
