To complete the table for Nitrogen:

  1. The atomic number of nitrogen is 7, which means it has 7 protons.

  2. The mass number is given as 14. The mass number is the sum of protons and neutrons. Since nitrogen has 7 protons, the number of neutrons can be calculated as follows:

    \[ \text{Neutrons} = \text{Mass Number} - \text{Protons} = 14 - 7 = 7 \]

  3. In a neutral atom, the number of electrons is equal to the number of protons. Thus, nitrogen has 7 electrons.

Putting this all together, here's the completed row for Nitrogen:
