Explanation:

• Count the number of electrons in the orbital diagram.
• The 1s orbital has 2 electrons.
• The 2s orbital has 2 electrons.
• The 2p orbitals have 5 electrons (2 + 2+ 1).
• Total electrons = 2 + 2+ 5 = 7.
• The atomic number of an element is equal to the number of electrons in a neutral atom.
• Nitrogen (N) has an atomic number of 7.
