Isang multivalent na hindi metal na kabilang sa grupo ng nitroheno, ang posporo ay kadalasang matatagpuan sa mga di-organikong batong phosphate. Ang Elementong posporo ay may dalawang uring laganap - puting posporo at pulang posporo. Bagamat ang ibig-sanihin ng salitang "phosphorescence" ay lumiwanag matapos ang pag-ilaw, mula sa salitang posporo, ang ilaw ng posporo ay nagmumula sa pag-o-oksihena ng puti-(ngunit di pula)-ng posporo at dapat tinatawag na chemiluminescence.

Dahil sa mataas nitong reaktibidad, ang posporo ay hindi kailanman nahahanap bilang malayang elemento sa kalikasan ng Daigdig. Ang kaunaunahang uri ng posporo (puting posporo, noong 1669) ay naglabas ng mahinang ilaw matapos matamaan ng oksiheno— kaya't binansagan itong (mula sa mitolohiyang Griyego) Φωσφόρος, na ang ibig-sabihin ay "tagadala ng liwanag" (wikang Latin: Lucifer), na sinasagisag ang "Tala ng Umaga", ang planetang Venus.

Ang posporo ay bahagi ng DNA, RNA, ATP, pati na ang lipidong-posporo na bahagi ng mga cell membranes. Ito ay isang esensyal na elemento para sa lahat ng buhay na cell. Karaniwan din itong makikita sa mga pataba, pulbura, kremang pansipilyo, pestecide, mga sabon panglaba, at siyempre, sa mga posporo mismo.
