What does the map indicate is the water
hardness where you live?

If the soapy solution foams up quickly, creating a lot of suds, and the water below the suds layer is relatively clear, you probably have at least fairly soft water. If the solution does not foam up well, creating only a shallow layer of suds, and the water below the suds is cloudy, you likely have hard water.

explanation:

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
