# nitrogen number of electrons

nitrogen 17 is an isotope of nitrogen with atomic number 7 and mass number 17. all nitrogen atoms have 7 protons [because the atomic number for all isotopes of nitrogen is 7] number of neutrons = mass number - atomic number. For example, N 3-has a -3 charge; therefore, it has gained 3 electrons compared to the neutral state. The second shell holds 8 electrons. The chemical symbol for Nitrogen is N . Helium - two electrons. 1)About Nitrogen (a) mumber of protons (b) number of shells (c) number of electrons (d) number of valence electrons 2)About Carbon (a) number of protons (b) number of shells (c) number of electrons (d) number of valence electrons I need a correct answer please. For most elements, a full outer shell is eight electrons. To find the number of electrons in an ion, just take the number of electrons it usually has, and add it to the additive inverse of the ionic charge. An example of a stable molecule with an odd number of valence electrons would be nitrogen monoxide.
