HF is a very strongly reactive acid that can break down lots of oxides and can etch glass.CrimpJiggler said:Ygggdrasil: that explains it, thanks.
Highway: So the F- ion is uncommon is it? I've read that HF is a weak acid but I don't know what its dissociation constant. Are you saying that HF doesn't actually dissociate at all?
CrimpJiggler said:Nitrogen is a lewis base because it has a lone pair of electrons with which to form bonds with electrophiles. Oxygen has 2 lone pairs of electrons and halogens have 3. Why doesn't oxygen use any of its spare pairs of electrons to react with electrophiles?

Nitrogen is considered a basic element because it has a lower electronegativity value compared to oxygen and fluorine. This means that nitrogen is less likely to attract electrons towards itself, making it a weaker acid and therefore a basic element.
The electronegativity value of an element is a measure of its ability to attract electrons towards itself. Elements with lower electronegativity values are less likely to attract electrons, making them weaker acids and therefore basic in nature.
The atomic size and the number of valence electrons also play a role in determining the basicity of an element. Elements with larger atomic sizes and more valence electrons are more likely to donate electrons, making them basic.
Yes, elements in Group 1 and Group 2 of the periodic table, also known as the alkali and alkaline earth metals, are more likely to be basic due to their low electronegativity values and large atomic sizes.
Yes, nitrogen can act as an acid in certain situations, such as when it is bonded with more electronegative elements. Its electronegativity value is still lower than oxygen and fluorine, but it is high enough to make it a weak acid in these cases.
