Why do F- and OH- have negative S values? (Entropy)
And are they the only ones with negative S values?
And are they the only ones with negative S values?
The negative S values for F- and OH- ions are due to their high electronegativity and small size.
Electronegativity is a measure of an atom's ability to attract and hold onto electrons in a chemical bond.
Atoms with high electronegativity, like F- and OH-, have a strong attraction for electrons. This means they are less likely to give up electrons and have a negative S value.
Smaller atoms, like F- and OH-, have a stronger attraction for electrons because their outer electrons are closer to the nucleus. This results in a more negative S value.
A negative S value indicates that the ion is stable and less likely to undergo a chemical reaction. This is important in understanding the reactivity of different ions in chemical reactions.
