What elements does phosphorus react with?
Phosphorus reacts with all halogens to form phosphorus trihalides. Specifically, it reacts with fluorine: F2, chlorine: Cl2, bromine: Br2, and iodine: I2, to form respectively phosphorus(III) fluoride: PF3, phosphorus(III) chloride: PCl3, phosphorus(III) bromide: PBr3, and phosphorus(III) iodide: PI3.
Are phosphorus containing compounds safe or dangerous?
White phosphorus is extremely poisonous and in many cases exposure to it will be fatal. White phosphorus can cause skin burns. While burning, white phosphorus may cause damage to the liver, the heart or the kidneys.
Is phosphorus harmful to humans?
EFFECTS OF SHORT-TERM (LESS THAN 8-HOURS) EXPOSURE: White phosphorus burns in air and causes severe burns upon contact with skin or eyes. White phosphorus smoke will also cause eye and respiratory tract irritation. Other initial adverse health effects are primarily due to gastrointestinal irritation.
Does phosphorus react with other chemicals?
Phosphorus reacts with sulfur to form several sulfides that are used in the manufacture of organic chemicals and matches. It reacts with many metals and metalloids to form phosphides. Phosphorus atoms can bond with oxygen atoms to form ester groups.
Is phosphorus a chemical reaction?
Phosphorus is a chemical element with the symbol P and atomic number 15. Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on Earth.
Why is phosphorus the best element?
Phosphorus, the 11th most common element on earth, is fundamental to all living things. It is essential for the creation of DNA, cell membranes, and for bone and teeth formation in humans.
What are the harmful effects of phosphorus?
Too much phosphorus can cause increased growth of algae and large aquatic plants, which can result in decreased levels of dissolved oxygen– a process called eutrophication. High levels of phosphorus can also lead to algae blooms that produce algal toxins which can be harmful to human and animal health.
Is phosphorus a toxic chemical?
White phosphorus is extremely toxic to humans, while other forms of phosphorus are much less toxic. Inhalation exposure has resulted in respiratory tract irritation and coughing in humans.
What is the chemical composition of phosphate?

Phosphate/Formula
Is phosphorus harmful to the environment?
Is phosphorus a physical or chemical change?
Density (near r.t. ) Phosphorus is a chemical element with the symbol P and atomic number 15. Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on Earth.
Why is phosphorus an important element?
Phosphorus, the 11th most common element on earth, is fundamental to all living things. It is essential for the creation of DNA, cell membranes, and for bone and teeth formation in humans. In the past, as part of a natural cycle, the phosphorus in manure and waste was returned to the soil to aid in crop production.
What is phosphorus (P)?
Phosphorus is a nonmetallic chemical element of the nitrogen family or Group 15 of the periodic table with the symbol P and atomic number 15. They are collectively called pnictogen or pnictides from the Greek word choking.
What family does phosphorus belong to on the periodic table?
Phosphorus is found in Group 15 (VA) of the periodic table. The periodic table is a chart that that shows how chemical elements are related to each other. Phosphorus is part of the nitrogen family along with nitrogen, arsenic, antimony, and bismuth. Phosphorus was first discovered in 1669 by German physician Hennig Brand (ca. 1630-92).
What happens when Phosphorus reacts with sulfur?
Phosphorus reacts with sulfur to form several sulfides that are used in the manufacture of organic chemicals and matches. It reacts with many metals and metalloids to form phosphides. Phosphorus atoms can bond with oxygen atoms to form ester groups.
What is the oxidation number of phosphorus?
Phosphorus is used almost entirely in the form of compounds, usually in the oxidation states of +3, +5, and −3. Unlike nitrogen and various other members of the family, phosphorus tends to exhibit a preference for the +5 state.
