Phosphorus (P, Z=15). Phosphorus is a nonmetallic element that exists in several allotropic forms (see below). It is found in the Earth’s crust at a concentration of 1000 ppm, making it the 11th most abundant element.
Is phosphorus a metal nonmetal metalloid or noble gas?
After the nonmetallic elements are classified as either noble gases , halogens or metalloids (following), the remaining seven nonmetals are hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur and selenium.
Why is phosphorus a nonmetal?
The phosphorus generally shows +3 and -3 as its oxidation state as by removing three electrons or by adding three electrons it can achieve the stable electronic configuration. So the answer is reactive. Phosphorus is a very reactive non – metal .

Is California a nonmetal?
The chemical element Calcium (Ca), atomic number 20, is the fifth element and the third most abundant metal in the earth’s crust. The metal is trimorphic, harder than sodium, but softer than aluminium. ... It is less chemically reactive than alkaline metals and than the other alkaline-earth metals.
Does phosphorus glow?
Phosphorus is a chemical element with the symbol P and atomic number 15. ... The glow of phosphorus is caused by oxidation of the white (but not red) phosphorus — a process now called chemiluminescence.
Is PA a metal or nonmetal?
Protactinium (formerly protoactinium) is a chemical element with the symbol Pa and atomic number 91. It is a dense, silvery-gray actinide metal which readily reacts with oxygen, water vapor and inorganic acids.
Why does phosphorus exist as p4?
Answer: Phosphorus can form a P 4 white phosphorus tetrahedron because it can form three bonds . It can make a tetra-atomic P 4 molecule by sharing valency electrons with three other P atoms to complete its octet. ...
Why is palladium so valuable?
Why is palladium so expensive? ... While some obscure metals like rhodium are still more valuable, palladium has mainly traded above gold since 2019. As governments across the world are tightening pollution-related norms, the demand for emissions-reducing catalysts, in which palladium is used, has gone up sharply.
