because they form in compund where one atom loses electrons and other gains.
The phosphide ion is stable
The symbol for the most stable ion of sulfur is S2-.
The stable ion of iron has a charge of +2, also known as Fe2+.
The most stable ion of fluorine (F) has a charge of -1, known as fluoride ion. The most stable ion of bromine (Br) has a charge of -1 as well, known as bromide ion.
The most stable ion of sulfur is the sulfide ion (S^2-). This ion has a full valence shell, giving it greater stability compared to other sulfur ions.
The chemical symbol for the most stable ion of barium is Ba2+.
Na+ is the formula of the ion formed when sodium achieves a stable electron configuration.
The most stable ion of Xenon is Xe2+. This ion is formed by losing two electrons from the outermost shell of Xenon, resulting in a stable electron configuration similar to that of the noble gas krypton.
The symbol for the most stable ion of bromine is Br-, which is the bromide ion. Bromine typically forms anions by gaining one electron to achieve a stable electron configuration similar to a noble gas.
Fluorine will gain one electron to form F- (or fluoride) ion. Fluoride ion has a charge of -1.
A stable electron configuration for a chlorine ion can be achieved by gaining one electron. This would give the chlorine ion a full outer shell of electrons. The symbol for a stable chlorine ion with an extra electron would be Cl-.
To become more stable: positive+negative=neutral. Neutral is more stable than positive and/or negative.
