In the ammonium ion, ALL the hydrogen atoms are equivalent. A coordinate-covalent bond has formed between the nitrogen lone pair and a proton on the water molecule; of course we...

Consider methane, $CH_4$, a room temperature gas, $"boiling point"$ $=$ $-164$ $""^@C$, versus diamond or graphite, with melting points and boiling points so high as to be almost unmeasurable. The...
