Identify the group number of each element in the periodic table. The group number often indicates the number of valence electrons for main-group elements.
Recall that elements in Group 15 (also called Group V or 5A) typically have 5 valence electrons.
Check the position of each element: Carbon (C) is in Group 14, Nitrogen (N) is in Group 15, Oxygen (O) is in Group 16, and Neon (Ne) is in Group 18.
Since Nitrogen (N) is in Group 15, it typically has 5 valence electrons, which matches the question's requirement.
Therefore, the element with 5 valence electrons based on its group in the periodic table is Nitrogen (N).
