Each isotope has the same number of protons and electrons but a different number of neutrons.
A nitrogen atom has 7 protons, 7 electrons and 7 neutrons for the most common isotope
Elements are determined by their number of protons. Nitrogen has 7 protons but usually 7 neutrons as well. What you have here is a nitrogen isotope, an element with more or less neutrons than there are protons. Specifically, this is Nitrogen-15.
The isotope 7N15
Nickel has 28 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a nickel isotope = Mass number -28
7 protons 7 electrons 8 neutrons

Nitrogen 15 contains: 7 protons 8 neutrons 7 electrons "15" is added to the name because it is an isotope and contains inequal amounts of protons and neutrons (in this case, an extra neutron).

Nitrogen is made up of seven protons and seven electrons (I'm not 100% sure about the electrons part), and the number of neutrons varies depending on the isotope. (N21 has 14 neutrons, N8 has one neutron)
Nitrogen always has 7 protons, otherwise it is not Nitrogen. Nitrogen 20 means that there are 20 protons. Unless it has an ionic bond, then there are also 7 electrons. If it is an ion, then there are 10 electrons.
Calcium has 20 protons and electrons and a number of neutrons different for each isotope..
Helium has 2 protons, 2 neutrons, and 2 electrons.
The isotope 7N15
Nickel has 28 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a nickel isotope = Mass number -28
7 electrons = 7 protons and 14 - 7 neutrons for the N-14 isotope
The most abundant isotope has 7 each.
