Valence means the no. Of electrons that need to complete an octave ( it includes loss and gain of elections)
So in this there is no need of electron that the first octave is full.
So the valency is zero...

We know that only valence electrons take part in bond formation with different atoms.In the atom of 'X' element there are only two electrons since atomic number is 2. Thus, K shell is fully filled for this atom.Hence,its valency is zero. It will not react with other atoms of different elements
HOPE , IT HELPS ... ✌
