N
Nitrogen typically forms ions with a charge of -3.
The ion formed by chlorine is the "chloride" ion
Having recently needing to answer this question on an online homework, the answer is simpler than expected. The question is really just asking for the "symbol" of fluorine which is F- Another example would be if it asked, "Predict the ion formed by Na (sodium)." The answer would simply be Na+
Hydroxonium H3O+ ion is formed.
+1 Na+ ion is formed
when a p-n junction is formed electrons from the neutral N type goes to neutral P type. In the junction there will not be any electron or hole. In the junction because of earning electrons, P side becomes negative(ion) , & N side becomes positive(ion). So there will be a potential deference . This is known as the BARRIER......
Fluoride Ion
The ion formed by a calcium atom is called a calcium ion, which has a 2+ charge.
I predict that an ion of sodium will have a charge of plus one.
A hydrogen ion (H+)
The number of electrons are required to predict the charge of the ion.
-2 is the most common charge (sulphide ion).
