Identify Group 4A (also known as Group 14) on the periodic table. This group contains elements that have 4 valence electrons in their outermost shell.
Recall the elements in Group 4A: Carbon (C), Silicon (Si), Germanium (Ge), Tin (Sn), and Lead (Pb).
Match the given options to the elements in Group 4A. The options are Silicon (Si), Germanium (Ge), Phosphorus (P), and Carbon (C).
Note that Phosphorus (P) is in Group 5A, so it is not part of Group 4A.
Conclude that the correct element from the options in Group 4A is Silicon (Si), which is the name and symbol of the element in Group 4A.
