Eu - Europium
Atomic Weight: 151.965
Oxidation States: 3, 2
Electron Configuration: [Xe]4f7,6s2
Noble gas notations are used because the electron configuration of these noble gases in too long ... this short cut is used ...

Europium only has the s orbital as its highest energy level.
The d and f orbitals do not effect the electron dot notation.
So, it'll look like this:
Eu:
