Introduction: Today I will be talking about my element phosphorus. I will be explaining its properties, who discovered it, where it is on the table, and its physical appearance.

• Symbol: P

• Atomic Number: 15

• Atomic Mass: 30.974 (real number is actually 30.973762)

Melting point (in Cº) 44.1

Boiling Point (in Cº) 280.5

Normal state of matter at room temperature: (solid, liquid or gas) Solid

Metal, non-metal, or metalloid: non-metal

Rare or common: Common

Appearance: White (most dangerous); red (commonly used in matchsticks); and black (rare, but most stable). It is powdery, but in its natural state it is like a rock.

Where is it found? It is found in minerals called phosphates

Who discovered it and when? Hennig Brand in 1669, Hamburg, Germany. He discovered it on accident while performing an experiment with urine.

Origin of its name: From the Greek word phosphoros meaning bringer of light.

Industrial and Medicinal Uses:

• Phosphorus is used mainly in agriculture - in 2004, 95% of all global phosphorus production went to produce fertilizers, animal feeds, and chemical pesticides. Phosphorus is supposed to strengthen plants by promoting root development.

• Phosphorus is also in food additives - phosphorus is in basically every type of processed food you can imagine.

• Phosphorus is used to treat hypophosphatemia - low levels of phosphorus in the body and hypercalcemia - high blood calcium levels

Where is it on the periodic table?

Fun Facts:

- Basically all of us have seen phosphorus-it is the red tip on a match stick and on the side of a match box for lighting candles.

- We have phosphorus in our body-about 85% of phosphorus in our body is in our bones.

- Phosphorus is sometimes called the "devils element" because of its explosive properties and the fact that it was the 13th element discovered

In conclusion, I have to say I have really enjoyed researching phosphorus, and I have in general liked the unit on elements. It is really cool knowing that anyone can discover an element, and there is probably tons of new elements scientists have yet to discover. Now I will take questions.
