Verified step by step guidance1
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 (8), Boron (5), Carbon (6), and Nitrogen (7).
Match the atomic number 6 to the corresponding element, which is Carbon.
Understand that the atomic number uniquely identifies an element, so an element with 6 protons must be Carbon.
Therefore, the element with 6 protons in its nucleus is Carbon.
