If we take away the outermost electron, we now have a new set of outermost electrons being the 8 electrons in the 3s and 3p orbitals. Ron is correct in his assessment of semantics. Na, Mg and Al Are the Elements of the Same Period of Modern Periodic Table Having, One, Two and Three Valence Electrons Respectively.

A boron atom contains three valence electrons and a germanium electron has four valence electrons, so every boron atom added to the semiconductor creates a 

I valence electrons

The valence electrons of an atom determine the valency of that element. Valence electrons are generally regarded as being 'the outermost electrons' for a given atom. Therefore, with neutral potassium, there is one valence electron. If we take away the outermost electron, we now have a new set of outermost electrons being the 8 electrons in the 3s and 3p orbitals.
