WebThe pentavalency of a phosphorus atom in the backbone of PPEs makes it possible to conjugate functional groups, including charged groups through a phosphate (P–O) or a phosphoramide (P–N) bond as side chains. Starting from the parent polyphosphite, the P–H bonds can be readily converted for conjugation of different chemical structures. WebApr 11, 2024 · A single molecule of hydrogen phosphate contains three atoms of hydrogen, one phosphorus, and four oxygen atoms. P belongs to group 5 of the periodic table, therefore has 5 valence electrons. O belongs to the chalcogen group or group 6, hence has 6 valence electrons. A hydrogen atom has only an atomic number of 1, therefore the valency.
