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"
Take 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 polyatomic anion is a tightly bound group of atoms that behaves as a unit and has a negative charge.
A monatomic anion consists of a single atom with a negative charge.
Monoatomic ions are ions that consist of one atom. While polyatomic ions are ions of 2 or more atoms.
Binary ions are ions that have one charge
Multivalent ions have more than one charge
polyatomic ions are ions with a covalent bond
Monoatomic ion: contain only one element; ex.: H+, Cl-
Polyatomic ion: contain more than one element; ex.: SO42-
Yes. Mg2+ is a monatomic ion, but SO42- is a polyatomic ion composed of two elements, sulfur and oxygen.
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.
Nitrate
No, it is a salt made of 1 Ca2+ ion and 2 Cl- ions with no total net charge. Hope this helps
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
Copper is a monatomic ion.
No. The carbonate is a polyatomic ion with the formula CO32-
Helium is typically monatomic, even as an ion.
monatomic Ion- contains one atom polyatomic ion- contains more than one atom
Yes. Mg2+ is a monatomic ion, but SO42- is a polyatomic ion composed of two elements, sulfur and oxygen.
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.
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.
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.
Nitrate
nitrate
Ammonium, NH4+
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.
