Identify the element in question, which is germanium (Ge).
Determine the group number of germanium in the periodic table. Germanium is in group 14 (or IV) of the periodic table.
Recall that the group number for main group elements corresponds to the number of valence electrons for a neutral atom.
Since germanium is in group 14, it has 4 valence electrons.
Therefore, a neutral germanium atom has 4 valence electrons.
