Verified step by step guidance1
Understand that the Lewis dot structure represents the valence electrons of an element. Elements in the same group of the periodic table have the same number of valence electrons and thus similar Lewis dot structures.
Identify the group number of silicon in the periodic table. Silicon is in group 14, which means it has 4 valence electrons.
Recognize that elements in the same group will have the same number of valence electrons. Therefore, they will have the same Lewis dot structure.
Compare the given elements: Carbon, Oxygen, Germanium, and Phosphorus. Determine which of these elements is in the same group as silicon.
Conclude that Germanium, like Silicon, is in group 14 of the periodic table, and thus has the same Lewis dot structure with 4 valence electrons.
