Recall that the number of protons in the nucleus of an atom defines the element's atomic number.
Identify the atomic numbers of the given elements: Oxygen (O) has 8 protons, Nitrogen (N) has 7 protons, Boron (B) has 5 protons, and Carbon (C) has 6 protons.
Match the atomic number 6 to the element Carbon (C), since it has exactly 6 protons in its nucleus.
Understand that the atomic number is unique to each element and determines its position on the periodic table.
Therefore, the element with 6 protons in its nucleus is Carbon (C).
