Identify the element in question, which is nitrogen.
Recall that the number of protons in an atom is equal to its atomic number.
Look up the atomic number of nitrogen on the periodic table. The atomic number is typically found above the element symbol.
Understand that the atomic number represents the number of protons in the nucleus of an atom of that element.
Conclude that the atomic number of nitrogen is 7, which means a nitrogen atom has 7 protons.
