How many protons does nitrogen ion have?
How many protons does nitrogen ion have? 7 protons This tells us that in an atom of N there are 7 protons and 7 electrons. c. But we are considering the anion N3-. The 3- indicates that there are three more electrons than protons in this ion. How many electrons are present in a nitrogen ion? As the nitrogen element contains 5 valence electrons in the outermost shell, it needs 3 more electrons to complete its octet of 8 electrons. So 3 electrons are gained by nitrogen to form anion with -3 charge. So the resulting anion is N3−. How many electrons are in the ion N3 -? There are 16 valence electrons for the Lewis structure for N3-. What is a nitrogen ion called? N-‐3 is the ion formed from nitrogen and its name is nitride ion. How do you find electrons in an ion? The charge on the…
