What is the most interesting element on the periodic table?
What Is the Coolest Element?
- Carbon. Carbon is cool for several reasons. ...
- Sulfur. You usually think of sulfur as a yellow rock or powder, but one of the cool things about this element is that it changes color under different conditions.
- Lithium. All of the alkali metals react spectacularly in water, so why did lithium make the list while cesium did not?

What does the p 3 stand for in chemistry?

Why is phosphorus called the devil's element?
White phosphorus has been called the “devil's element” because it glows green in the dark and is pyrophoric. Because of its instability, white phosphorus is typically stored under water, in which it is barely soluble.
Which element is the letter p?

Is phosphorus harmful to humans?
Ingestion of elemental white or yellow phosphorus typically causes severe vomiting and diarrhea, which are both described as “smoking,” “luminescent,” and having a garlic-like odor. Other signs and symptoms of severe poisoning might include dysrhythmias, coma, hypotension, and death.
Does phosphorus explode?
Phosphorus spontaneously ignites on contact with air, producing toxic fumes (phosphorus oxides). Phosphorus reacts violently with oxidants, halogens, some metals, nitrites, sulfur, and many other compounds. This causes a fire and explosion hazard. Phosphorus reacts with strong bases to produce toxic phosphine gas.
What starts from P in chemistry?
phosphorus (P), nonmetallic chemical element of the nitrogen family (Group 15 [Va] of the periodic table) that at room temperature is a colourless, semitransparent, soft, waxy solid that glows in the dark.
What scientific word starts with P?

What makes phosphorus unique?
It glows in the dark and is spontaneously flammable when exposed to air. Red phosphorus is an amorphous non-toxic solid. White phosphorus is used in flares and incendiary devices. Red phosphorus is in the material stuck on the side of matchboxes, used to strike safety matches against to light them.
Why is red phosphorus illegal?
Because of its connection to meth production, the U.S. Drug Enforcement Administration regulates the sale of red phosphorus in the United States, along with white phosphorus and hypophosphorous acid (H3PO2).
Why is white phosphorus banned?
It is a weapon banned by the UN as it is used to make bombs more lethal. Its use in open areas is legal under international law, but air-dropping phosphorus over inhabited areas is prohibited, as it endangers civilians and can result in an indiscriminate attack due to the wide dispersion of the burning fragments.
What does red phosphorus do to the body?
Inhalation Exposure: Inhalation of Red-P dust causes respiratory tract irritation, coughing, and bronchitis. If contaminated with White-P, it can also cause liver or kidney damage. Skin (Dermal) Exposure: Prolonged and/or repeated contact with Red-P may cause irritation or dermatitis.
What phosphorus smells like?
What molecule am I? Phosphine, the simplest phosphorus hydride, is a colorless and extremely toxic gas. Some people think it smells like rotting fish; it reminds others of the odor of garlic.
Who created the periodic table?
The creator of the periodic table, Dmitri Mendeleev, in 1869 began collecting and sorting known properties of elements, like he was playing a game, while traveling by train.
What is PubChem working with?
PubChem is working with IUPAC to help make information about the elements and the periodic table machine-readable.
Can periodic table games be used for grade?
The periodic table game available on this page is for entertainment purposes only, and should not be used to grade students on their knowledge of chemical elements.
Does the Modern Periodic Table Change? If So, How and Who Does That?
The periodic table as we know it today is managed by the International Union of Pure and Applied Chemistry, or IUPAC (eye-you-pack).
What does P stand for in the periodic table?
P stands for phosphorus on the periodic table, it is the 15th element. P can also stand for pressure, when referring to the gas law PV=NRT where P is pressure, v is volume, n is moles of gas, r is the constant .0821 (atm), and T is Temperature (kelvin).
What does P stand for in chemistry?
P stands for the element phosphorus with the atomic number 15. Phosphorus exists in two major forms, red phosphorus and white phosphorus. It is a highly reactive element and so it never exists in free state on earth.
What is the atomic number of silicon?
It's come after silicon whose atomic number is 14.
What does the P symbol stand for?
P is the atomic symbol for phosphorus. As such, it is sometimes used by biochemists in structural shorthand enclosed in a small circle to stand for the phosphate anion (PO4)3-
Who discovered phosphorus?
Phosphorus was first made by Hennig Brandt at Hamburg in 1669 when he evaporated urine and heated the residue until it was red hot, whereupon phosphorus vapour distilled which he collected by condensing it in water. Brandt kept his discovery secret, thinking he had discovered the Philosopher’s Stone that could turn base metals into gold. When he ran out of money, he sold phosphorus to Daniel Kraft who exhibited it around Europe including London where Robert Boyle was fascinated by it. He discovered how it was produced and investigated it systematically. (His assistant Ambrose Godfrey set up his own business making and selling phosphorus and became rich.)
