Why can arsenic replaces phosphorus?
Here, we present evidence that arsenic can substitute for phosphorus in the biomolecules of a naturally occurring bacterium. Arsenic (As) is a chemical analog of P, which lies directly below P on the periodic table. Arsenic possesses a similar atomic radius, as well as near identical electronegativity to P (5).
What is the charge of phosphate?
-3 charge
From our table of polyatomic ions we know that phosphate has a -3 charge. Since there are two phosphate ions, the total negative charge is -6.
What is the oxidation state of arsenic in the arsenate ion?
In chemistry an arsenite is a chemical compound containing an arsenic oxoanion where arsenic has oxidation state +3.
How many charges does arsenic have?
Arsenic (+3) is arsenic with three fewer electrons than protons, giving it a plus three positive charge; arsenic (+5) is arsenic with five fewer electrons than protons, giving it a plus five positive charge.

What is the difference between arsenic and arsenate?
Arsenate (As5+) is a common form of arsenic found in water supplies, and is generally less acutely toxic than arsenite (As3+), which is the other common oxidation state discussed below.
Can we substitute arsenic As for phosphorus?
It is not possible to substitute arsenic for phosphorus in humans, but it has been known for some time that there are types of bacteria, often called extremophiles, that can survive in many kinds of extreme environments.
How is arsenic different from phosphorus?
Arsenic is a chemical element having atomic number 33 and chemical symbol As. Phosphorous is a chemical element having the atomic number 15 and chemical symbol P. The key difference between arsenic and phosphorous is that arsenic is a nonmetal whereas phosphorous is a metalloid.
Why is phosphorus a negative 3 charge?
Therefore it contains 5 valence electrons in its isolated neutral atom. if this neutral atom gains 3 more electrons, then it achieves a stable noble gas electron configuration identical to argon (Ar). This results in a phosphide anion with a charge of -3.
Why is phosphate ion charge 3?
phosphite have a -3 charge when it has one fewer oxygen atom than phosphate, which has a negative charge of 1. The chemical formula for phosphite ion is PO3−3 P O 3 3 − . In this case, the oxidation state of phosphorus is equal to +3. The chemical formula for phosphate ion is PO3−4 P O 4 3 − .
What are the oxidation numbers of each element in the arsenate ion AsO₄³ ⁻?
As =−3+8=+5.
How many valence electrons are in the arsenate ion?
Total number of electrons of the valance shells of AsO
Arsenic is a group VA element and has only five electrons in its valence shell.
What is the charge for phosphorus?
3-
(b) By referring to a periodic table or table of elements, we see that phosphorus (symbol P) has an atomic number of 15. Thus, each atom has 15 protons. The mass number of the ion is 15 + 16 = 31. Because the ion has 15 protons and 18 electrons (three more electrons than protons), its net charge is 3-.
What elements form 2+ ions?
The alkaline earth metals (red) always form +2 ions.
Is arsenic positive or negative charge?
Is arsenic positive or negative?
The most common and stable forms of arsenic in nature are arsenite, also called or arsenic (+3), and arsenate, or arsenic (+5).
What is the meaning of arsenate?
Definition of arsenate
: a salt or ester of an arsenic acid.
How are arsenic and phosphorus similar?
Arsenic is a chemical analog of phosphorus, just as copper is to iron, mentioned above. It sits just below phosphorus on the periodic table, making it a non-metal, and implicating similar atomic radii, the same number of valence electrons, and nearly identical electronegativity and orbital configurations.
Is phosphorus based life possible?
Phosphorus is essential for creating life’s building blocks, such as DNA, ATP, and lipids. But a long-standing problem has been where early life would have gotten its supply of phosphorus molecules, which typically are found only in tiny amounts in the natural environment.
Why do phosphorus P and arsenic as have similar chemical properties?
The outer-shell similarity of the two elements suggests that arsenic, like phosphorus, can form three covalent bonds per atom, with an additional lone pair of electrons left unbonded.
Can we substitute arsenic as for phosphorus?
