What do you think about our current forms of recycling and why ?

i think its great because we reuse more stuff instead of making more stuff and we save the environment

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)

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.
