Elemental nitrogen has no charge.
In ammonia (NH3) and ammonium ions (NH4+) it has a oxidation value of -3 (and actually only a partial negative charge as part from a polar covalent, non-ionic bond).
In Nitrate (NO3-) its oxidation value is +5, in nitrite +3 (but only a partial positve charge in both)
nitrogen
The neutral nitrogen atom and the neutral nitrogen molecule has no net charge because they are made up of equal numbers of positively charged protons and negatively charged electrons. If the nitrogen atom or molecule gains or looses and electron it becomes a positively or negatively charged ion.
A neutral nitrogen atom has 7 protons and 7 electrons, and has no charge.
The charge of Cu3N is 0, as the compound has a neutral overall charge. Each copper atom has a +1 charge, and each nitrogen atom has a -3 charge, leading to a balanced compound with no net charge.
To achieve a noble gas configuration, nitrogen needs to gain three electrons to have a completely filled outer shell like neon. This would give it a charge of -3 since each gained electron carries a negative charge.
There is no charge. Nitrogen-15 is an isotope, which refers to the number of neutrons. Neutrons do not have a charge.
nitrogen
The total charge of two nitrogen anions is -2. Nitrogen typically forms anions with a charge of -3, so two nitrogen anions would have a total charge of -6.
The formal charge of the nitrogen atom in NCl3 is 0.
The formal charge on the nitrogen atom in the nitrosyl ion (NO^-) is 0. Oxygen is more electronegative than nitrogen, so it takes on the negative formal charge while nitrogen carries a positive formal charge.
All protons -- whether in nitrogen or elsewhere -- are identical, and all have a positive charge.
nitrogen
Nitride ions have a charge of -3.
Nitrogen typically forms an ion with a charge of -3. This is because nitrogen typically gains three electrons to achieve a full outer electron shell, resulting in a charge of -3.
A nitrogen ion with 10 electrons would have a charge of +3, as nitrogen normally has 7 electrons and a neutral nitrogen ion would have 7 electrons. By having 10 electrons, it has lost 3 electrons, resulting in a +3 charge.
Nitrogen would have a neutral charge and eight valence electrons.
The charge on nitrogen monoxide, also known as nitric oxide, is neutral. It contains one nitrogen atom and one oxygen atom, each with their own electronegativities, resulting in a balanced distribution of electrons and no overall charge.
