What is the difference between a monatomic ion and a polyatomic ion?

∙ 14y ago
A monoatomic ion has only one atom examples are chloride, Cl-, fluoride, F-, sodium Na+
A polyatomic ion has more than one, e.g sulfate SO42-, nitrate, NO3-, mercurous, Hg22+
Poly is from the Greek and means "many"

∙ 11y agoTake a look at your prefixes. "Mono-" means 1; "poly-" means many, or more than 1. A monatomic ion is an ion formed from 1 atom. Example: any single atom that reacts in an ionic bond, like Na+ or Cl-. A polyatomic ion is a group of atoms that act like one, with a single charge. Example: the nitrate polyatomic NO3- or the ammonium polyatomic NH4+. In a bonding scenario, the polyatomics act just like monatomics, and you simply balance the charges accordingly to get the correct formula.

A monatomic anion consists of a single atom with a negative charge.

Does MgSO4 contain polyatomic ions?
Yes. Mg2+ is a monatomic ion, but SO42- is a polyatomic ion composed of two elements, sulfur and oxygen.
What does the ide ending in a polyatomic ion mean?
The ide ending in a polyatomic ion actually has no practical meaning involved. The polyatomic compounds that do contain the ide ending have it because they were thought to be monatomic at one time.
Which polyatomic ion forms a neutral compound when combined with a group 1A monatomic ion in a 1 to 2 ratio?
Nitrate
Is CaCl2 polyatomic ion?
No, it is a salt made of 1 Ca2+ ion and 2 Cl- ions with no total net charge. Hope this helps
Which polyatomic ion forms a neutrak compound when combined with a group 1A monatomic ion in a 1 1 ratio?
Since Group 1A monatomic ions have a charge of 1+, only a polyatomic ion with a charge of 1- can combine to form a compound in which the monatomic ions and polyatomic ions are present in a 1 to 1 ratio. The following polyatomic ions with a charge of 1- can form a neutral compound when combined with a group of 1A monatomic ion in a 1 to 1 ratio.acetate - C2H3O2-bicarbonate (or hydrogen carbonate) - HCO3-bisulfate (or hydrogen sulfate) - HSO4-chlorate - ClO3-chlorite - ClO2-cyanate - OCN-cyanide - CN-dihydrogen phosphate - H2PO4-hydroxide - OH-nitrate - NO3-nitrite - NO2-perchlorate - ClO4-permanganate - MnO4-thiocyanate - SCN- Source: http://chemistry.about.com/od/chartstables/tp/common-polyatomic-ions.htm
Is copper a monoatomic or polyatomic ion?
Copper is a monatomic ion.
Is carbonate ion a monatomic ion?
No. The carbonate is a polyatomic ion with the formula CO32-
Is helium a polyatomic ion?
Helium is typically monatomic, even as an ion.
What is the name for an ion that contains more than one type of element?
monatomic Ion- contains one atom polyatomic ion- contains more than one atom
Does MgSO4 contain polyatomic ions?
Yes. Mg2+ is a monatomic ion, but SO42- is a polyatomic ion composed of two elements, sulfur and oxygen.
What are the similarities and differences between polyatomic monatomic ions?
They both are charged particles. However, a monatomic ion forms from a single atom, while polyatomic ions are formed from a group of atoms of more than one element that are covalently bonded.
What formula for a compound has monatomic and polyatomic ions present?
The answers have to be include monatomic and plyatomic ions present and ratio between positive and negative ions is one to two, and a group IIA element that loses one half of its total electrons upon ion formation is present, and the sum of the atomic numbers for the two elements involved in the polyatomic ion is 13.
What does the ide ending in a polyatomic ion mean?
The ide ending in a polyatomic ion actually has no practical meaning involved. The polyatomic compounds that do contain the ide ending have it because they were thought to be monatomic at one time.
Which polyatomic ion forms a neutral compound when combined with a group 1A monatomic ion in a 1 to 2 ratio?
Nitrate
Which polyatomic ion forms a neutral compound when combined with a group 17 monatomic ion in a 11 ratio?
Ammonium, NH4+
Which polyatomic ion forms a neutral compound when combined with a group 1a monatomic ion in a 1 2 ratio?
nitrate
Is S2-a polyatomic ion?
No. S2- is a monatomic ion. A polyatomic ion contains at least two atoms. You can identify a polyatomic ion as it will have the symbols for more than one element (OH-), a subscripted number (O22-), or a combination of the two (CO32-). The superscript in the ion only indicates the charge.
