The ion N³⁻ is called the azide ion. In its neutral state, it occurs as the element Nitrogen. The atomic number of Nitrogen is 7. When it turns into an anion (negatively charged ion), it gains 3 more electrons. That's why its net charge becomes -3. It means that the protons is still 7, but the electrons are now 10.
Overall charge = +7 + -10 = -3
Answer:
for example, a carbon atom weighs less than 2 × 10−23 g, and an electron .... Determine the numbers of protons, neutrons, and electrons in one of these iodine anions. ...
