What does 2s1 mean in chemistry?
Helium has both of its electrons in the 1s orbital (1s2). In Li the electron configuration is 1s2 2s1, which tells us that
the electron is being removed from a 2s orbital
.

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

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

- The electron configuration of an atom is written with the help of subshell labels.
- These labels contain the shell number (given by the principal quantum number), the subshell name (given by the azimuthal quantum number) and the total number of electrons in the subshell in superscript.
