Alkali metals exist only as salts.
Yes, hydrogen bonds in pure water break and reform constantly due to the constant movement of water molecules. This dynamic process is essential for the unique properties of water, such as its high surface tension and specific heat capacity.
Yes it is available in its pure form
Nope. Mercury is normally a liquid. Many acids and other compounds are routinely liquid. Blood can be 'pure.'
Ammonia is a compound and so can exist as a pure substance. Household ammonia is not pure. It is a 3% ammonia solution. The other 97% is water. Pure ammonia is very dangerous.
