hello there!

phosphorous is a very reactive non metal

Phosphorus is a chemical metal P and atomic number 15. Elemental phosphorus exists in two major forms, white  and , but because it is highly reactive , phosphorus is never found as a free element on Earth. It has a concentration in the Earth's crust of about one gram per kilogram (compare copper at about 0.06 grams). In minerals, phosphorus generally occurs as phosphate.

Elemental phosphorus was first isolated as white phosphorus in 1669. White phosphorus emits a faint glow when exposed to oxygen  hence the name, taken from Greek mythology, Φωσφρος meaning "light-bearer" referring to the " Morning, the planet Venu. The term " phosphorescence ", meaning glow after illumination, derives from this property of phosphorus, although the word has since been used for a different physical process that produces a glow. The glow of phosphorus is caused  of the white (but not red) phosphorus — a process now Together with nitrogen, arsenic, antimony, and bismuth, phosphorus is classified as a pnictogen

i hope this helps

goodluck!

Hello,

Phosphorus is a chemical element with the symbol 'P' and atomic number 15. It exists in two different forms viz. white phosphorus and red phosphorus. It is a highly reactive metal and that's why it is never found as a free element in earth. So, it is a very reactive non-metal.

Hope this helps!
