How many electrons are in the outermost shell of an atom of phosphorus P use the periodic table?
So… for the element of PHOSPHORUS, you already know that the atomic number tells you the number of electrons. That means there are 15 electrons in a Phosphorus atom. Looking at the picture, you can see there are two electrons in shell one, eight in shell two, and five in shell three.
How many valence electron does P have?
5 valence electrons
How are 15 electrons arranged in a phosphorus atom?
When we write the configuration we’ll put all 15 electrons in orbitals around the nucleus of the Phosphorus atom. In writing the electron configuration for Phosphorus the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for Phosphorous go in the 2s orbital.
How are electrons arranged in a phosphorus atom?
Phosphorus has electron configuration, 1s22s22p63s23p3. The highest-numbered shell is the third shell (3s23p3): 2 electrons in the 3s subshell and 3 electrons in the 3p subshell. That gives a total of 5 valence electrons. Examine the electron configuration of neutral calcium atom (Exercise 2.6.
What element is 3p6?
Electron Configurations
| A | B |
|---|---|
| Aluminum | 1s2 2s2 2p6 3s2 3p1 |
| Sulfur | 1s2 2s2 2p6 3s2 3p4 |
| Chlorine | 1s2 2s2 2p6 3s2 3p5 |
| Argon | 1s2 2s2 2p6 3s2 3p6 |
Will phosphorus be able to form bonds easily with other elements?
INTRODUCTION: Phosphorus can form bonds with many other elements. ORGANIC CHEMISTRY: Phosphorus can form bonds readily with oxygen, nitrogen and sulfur; also it can form bonds with carbon much less readily; but the phosphorus-carbon bonds are inert that they do not break readily even though not very strong.
Can phosphorus form a triple bond?
The outer electrons of phosphorus cannot form strong triple bonds, because the distance between the electrons and the atomic nuclei is greater in phosphorus than in nitrogen. Therefore the paired electrons can easily separate. The phosphorus atom often forms compounds in which phosphorus is bonded to five other atoms.
Can phosphorus kill you?
But, strip the oxygen atoms away, and we are left with a dreadfully powerful element that is poisonous, glows in the dark with an eerie green light, and is flammable – catching fire on its own when left exposed to air. Besides, white phosphorus can cause painful diseases and even kill in a number of ways.
What other elements does phosphorus bond with?
Phosphorus atoms can bond with oxygen atoms to form ester groups. These can bond with carbon atoms, yielding a large number of organic phosphorus chemicals. These are found in many important biological processes.
Why is phosphorus called the devil’s element?
Some texts refer to phosphorus as the “Devil’s Element” because of its eerie glow, tendency to burst into flame, and because it was the 13th known element. Like other nonmetals, pure phosphorus assumes markedly different forms. There are at least five phosphorus allotropes.
Why is phosphorus written P4?
Phosphorus can form a P4 white phosphorus tetrahedron because it can form three bonds, while sulfur can only form two bonds. Therefore sulfur forms rings and chains only. The most stable allotrope of phosphorus, red phosphorus, is a cross-linked, polymeric chain of atoms.
Why is phosphorus very reactive?
White phosphorus is structured as individual molecules of 4 atoms bonded together to form a tetrahedron. The P4 rings are held to each other by physical bonding (like other molecular substances) but no chemical bonding. These P4 rings are an unstable arrangement which makes the white phosphorus extremely reactive.
Which is the most reactive species of phosphorus?
White phosphours is the most reactive (due to the presence of discrete P4 molecules) while black phosphorus is the least reacrive. Thus, white phosphorus is stored under water to protect it from air while red and black phosphorus are stable in air.
Which form of phosphorus is most reactive?
white phosphorus allotrope
Which allotropic form of phosphorus is the most reactive?
White phosphorus
Which is the most reactive allotrope of phosphorus Why?
Which phosphorus is more reactive and why?
White phosphorus is more reactive than red phosphorus because red phosphorus has polymeric structure . it consists of chains of P4 linked together .
Which allotrope of phosphorus is less reactive?
Black phosphorus
Why black phosphorus is most stable?
Black phosphorus is the most stable form; the atoms are linked together in puckered sheets, like graphite. Because of these structural similarities black phosphorus is also flaky like graphite and possesses other similar properties.
What is violet phosphorus used for?
Phosphorus is a common element with many industrial uses. Unfortunately, it is a key ingredient in making the street drug methamphetamine.
Is red phosphorus illegal?
It is unlawful for any person knowingly or intentionally to possess or distribute red phosphorus, white phosphorus, or hypophosphorous acid, knowing, or having reasonable cause to believe, these substances will be used to illegally manufacture methamphetamine.
How dangerous is red phosphorus?
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.
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). If you prefer not to work with urine, you can also refine phosphorus from bone ash or phosphorus-rich minerals.
How does phosphine gas kill you?
“When this chemical comes in contact with water, it creates phosphine gas, which is highly poisonous and can cause pulmonary edema and respiratory failure.” Pulmonary edema occurs when fluid collects around the lungs and makes it difficult or impossible to breathe.
Why is red phosphorus used in matches?
A small amount of the red phosphorus on the friction surface is converted into white phosphorus. The heat ignites the phosphorus that has reached the match head of the match when rubbing. This triggers the reaction between sulfur or antimony sulfide and oxygen.
How do you dispose of red phosphorus?
According to the United Nation’s treatment and disposal methods for wastes containing phosphorus, the two recommended methods of disposal are incineration and open burning (HSDB 1993). In the open burning method, the waste should be mixed with wet earth, allowed to dry, and ignited in a remote place.
How toxic is white phosphorus?
White phosphorus is used in the manufacture of munitions, pyrotechnics, explosives, smoke bombs, in artificial fertilizers, and rodenticides. White phosphorus is extremely toxic to humans, while other forms of phosphorus are much less toxic.
