A nitrogen atom has 7 protons. Therefore a nitrogen molecule has 14 protons.

The atomic number of an atom tells us its number of protons. Nitrogen's atomic number is 7. Thus, it has 7 protons.
The number of protons in an atom will always be the same as the atomic number. Luckily, the periodic table is organized by increasing atomic number, so finding how many protons are in nitrogen just becomes an exercise of reading the periodic table. In this case, the atomic number of nitrogen is 7.See periodic table below.
A neutral nitrogen atom has 7 protons. This is because nitrogen has an atomic number of 7 and each atom has the same number of protons as its atomic number. Therefore a neutral nitrogen atom would have 7 protons.
The number after the "N", 15, is the mass number. The mass number is the sum of the number of protons and the number of neutrons. So, if you find a periodic table, you can find the atomic number, which is the same as the number of protons. Because the atomic number of nitrogen is 7, it has 7 protons. Then we take the mass number (protons + neutrons) and subtract the number of protons to find the number of neutrons. 15 - 7 = 8 neutrons in 15N.
The atomic number for nitrogen is 7, meaning that it has 7 protons. In order for it to remain as nitrogen, the number of protons in it must always be 7. If, for example, the number of protons were to increase to 8, it would no longer be nitrogen; it would then be oxygen.

Protons = atomic number EX: Nitrogen has 7 protons
The answer is 7. The amount of protons is always the atomic number of the element. If the protons (atomic number) changes then the element changes

The element which has the smallest atomic number has the smallest number of protons. In this case, argon has a proton number of 18 (therefore it has 18 protons in each atom), but nitrogen has fewer protons - it has a proton number of just 7, meaning that it has seven protons per nitrogen atom.
The nitrogen isotope has more protons, because it has a higher atomic number.
The nitrogen has 7 protons. your welcome!
7 protons , 8 neutrons and 7 electrons in the neutral atom. Nitrogen has an atomic number of 7. The atomic number is the number of protons in the nucleus. In the neutral atom this is also the number of electrons . The "15" in nitrogen-15 is the mass number, the total number of protons and neutrons in the nucleus. Taking 7 from 15 there are therefore 8 neutrons in nitrogen-15.
