Detailed explanation-1: -Phosphorus is a very reactive non-metal .
Detailed explanation-2: -Phosphorus is a very reactive non-metal, when exposed to air it starts reacting vigorously, therefore it is kept in water.
Detailed explanation-3: -The most reactive nonmetal is fluorine. Fluorine is a halogen, which is Group 17 on the periodic table, and the halogens are the most reactive nonmetals.
Detailed explanation-4: -Answer: (a) Phosphorus is a very reactive non-metal.
Detailed explanation-5: -Phosphorus is too reactive to be found in nature in its elemental state. In particular, white phosphorus is reactive with oxygen, and phosphorus is most commonly found in its highest formal oxidation state (+5), as in phosphate (PO43−) salts or in organophosphorus compounds.
