Number of Electrons, Protons, and Neutrons in N3- Ion

To determine the number of electrons, protons, and neutrons in the N3- ion, we need to understand the electronic configuration and the concept of ions.

Electronic Configuration of Nitrogen
Nitrogen (N) has an atomic number of 7, which means it has 7 protons and 7 electrons in its neutral state. The electronic configuration of nitrogen can be represented as 1s^2 2s^2 2p^3.

Ions and Charge
Ions are formed when atoms gain or lose electrons. The charge of an ion is determined by the number of electrons gained or lost. In the case of the N3- ion, it means that nitrogen has gained 3 electrons.

Number of Electrons in N3- Ion
Since nitrogen has gained 3 electrons to form the N3- ion, we need to add these extra electrons to the original number of electrons.
7 (original electrons) + 3 (additional electrons) = 10 electrons

Therefore, the N3- ion has 10 electrons.

Number of Protons in N3- Ion
The number of protons remains the same in an ion as it does in the neutral atom. Therefore, the N3- ion still has 7 protons.

Number of Neutrons in N3- Ion
Neutrons are electrically neutral particles found in the nucleus of an atom. They do not participate in the formation of ions. Therefore, the number of neutrons in the N3- ion remains the same as in the neutral nitrogen atom, which is 7 neutrons.

Summary
- The N3- ion has 10 electrons, 7 protons, and 7 neutrons.
- Nitrogen (N) has 7 electrons, 7 protons, and 7 neutrons in its neutral state.
- When nitrogen gains 3 electrons to form the N3- ion, the number of electrons increases to 10.
- The number of protons and neutrons remains the same in the N3- ion as in the neutral nitrogen atom, which is 7 protons and 7 neutrons.
