If it contains a number in its formula (such as in peroxide, O2-) it is polyatomic as this means there are more than one atom of the same type.
If it contains more than one element, which you would find if there is more than one capital later. (such as in hydroxide, OH-).
If both are true, it is polyatomic (as in permanganate MnO4-).
If it ends in -ite or -ate it is polyatomic (as in sulfate, SO42- and sulfite, SO32-)
If the name of the ion does not contain the name of an element, it is polyatomic (as in cyanide CN- or ammonium NH4+).
What else can I help you with?
Why are some ions called polyatomic ions?
Polyatomic means many atoms. Anions and cations may be polyatomic:-Polyatomic anions include sulfate ion, SO4-, and nitrate NO3-Polyatomic cations include ammonium ion, NH4+
How does an binary compound different from an polyatomic ion?
A binary compound is a chemical compound made up solely of 2 elements, for example P2O5, Na2O KCl. (The bonding is not relevant- it could be covalent or ionic.)A polyatomic ion is a cation or anion that contains more than one atom. Most contain 2 different elements. For examplepolyatomic anions:- [SO4]2-, [NO3]-polyatomic cation:-[ NH4]+ , [Hg2]2+
What nonmetallic element is the most abundant?
I believe that the most common elements found in nature are the following: Carbon (C) Oxygen (O) Sodium (Na) Nitrogen (N) Hydrogen (H) Ones commonly used by humans are: Aluminium (Al) Iron (Fe) Copper (Cu) Zinc (Zn) Magnesium (Mg) Titanium (Ti) Chlorine (Cl) There are also some very common polyatomic ions and compounds such as: Carbon Dioxide (CO2) Oxygen Gas (O2) Sulfates (SO4) Sulfides (SO3) Salt/Sodium Chloride (NaCl) Carbonates (CO3) Alcohol (CH3COOH) Glucose (C6H12O6) There are many more common compounds, atoms, and polyatomic ions.
A negatively charged atom or group of atoms?
Unless they are ions, atoms are neutrally charged. The negatively charged electrons orbitting the nucleus neutralized the positive charges of the protons in the nucleus. neutrons do not have an electrical charge. ions are the exception to this, as they have either added or removed orbitting electrons. if an atom has electrons removed, then it is a positively charged cation. most metals form positively charged ions. if electrons are added, then it is a negatively charged anion. most non-metals form negatively charged ions.
Using the periodic chart indicate the most common charge of phosphorous?
Phosphorus is number 15 on the Periodic Table of Elements. The most common charge is -3 because it needs three more electrons to fill it's outer shell.
Are a vast majority of polyatomic ions cations?
No. Most polyatomic ions are anions.
What are the usual endings for the names of polyatomic ions?
The usual endings for polyatomic ions are "-ate" and "-ite." The "-ate" ending signifies the ion with the larger number of oxygen atoms, while the "-ite" ending signifies the ion with one less oxygen atom.
What element do most polyatomic ions contain?
Oxygen
Are polyatomic ions positively charged?
Most polyatomic ions have a negative charge. There are only 2 positive polyatomic ions; Mercury(I) ion and Ammonium ion. False.
Polyatomic ions always carry a positive charge?
False. Polyatomic ions can carry either charge. For example, consider the sulphate ion - SO42- or the hydroxide ion, OH-. Negative polyatomic ions are, in fact, generally more common than positive ones.
Characteristic is shared by most simple polyatomic ions?
They are anions
What polyatomic ions are in soda?
The most common polyatomic ions found in soda are carbonate (CO3^2-), bicarbonate (HCO3^-), and phosphate (PO4^3-). These ions are often present in ingredients like carbonated water and various additives used in soda production.
What element do most of the polyatomic ions have in the formula?
Examples: oxygen, sulfur, carbon, phosphorus etc.
Do Polyatomic ions always contain oxygen?
In most of the cases it is true but SCN- , Transition metals complex ions and some organic poly atomic ions do not contain oxygen.
Which polyatomic ion has 4 oxygens?
The three most common such ions probably are sulfate, with the formula SO4-2, chromate, with the formula CrO4-1, and perchlorate, with the formula ClO4-1.
How are polyatomic ions usually charged?
It depends but most are negative, e.g. nitrite, sulfate, nitrate, sulfite, chlorite, phosphate, phosphite, permanganate, chromate, dichromate etc. There are however, polyatomic ions that are positively charged.
Which of these pairs of elements is most likely to be part of a polyatomic ion?
The pair of elements most likely to be part of a polyatomic ion is sulfur (S) and oxygen (O). This combination often forms polyatomic ions such as sulfate (SO4^2-) or sulfite (SO3^2-).
