A polyatomic ion is a compound made up of multiple atoms and has an overall charge. Examples of these include ammonium (NH4+) and sulfate (SO42-). Oxyanions are a specific subset of polyatomic ions and they are so named because they contain oxygen (oxy-) and have an overall negative charge (anion). Examples of oxyanions are sulfate (SO42-), phosphate (PO43-), nitrate (NO3-), and chlorate(ClO3-). They each have derivatives depending on the number of oxygen atoms they have. For example, from sulfate (SO42-), we can have sulfite (SO32-), hyposulfite (SO22-), and persulfate (SO52-) (aka peroxomonosulfate to distinguish it from peroxodisulfate, S2O82-). The importance of oxyanions is that they form acids when they are dissolved in water. For example, sulfate forms sulfuric acid, sulfite forms sulfurous acid, hyposulfite forms hyposulfurous acid, and persulfate forms persulfuric acid (peroxomonosulfuric acid).

What is the symbol of a monatomic ion?
The symbol of a monatomic ion is the elemental symbol of the element followed by a superscript representing the charge of the ion. For example, Na+ represents a sodium ion with a +1 charge.
What is one atom ion called?
A one-atom ion is called a monatomic ion. It is formed when an atom gains or loses electrons, resulting in a net positive or negative charge.
What monatomic ion is found in all acids?
This ion is the hydrogen cation.
What is The charge of a monatomic ion called?
Oxidation Number
Which polyatomic ion forms a neutral compound when combined with a group 1a monatomic ion in a 1 2 ratio?
The sulfate ion (SO4^2-) forms a neutral compound when combined with a group 1a monatomic ion in a 1:2 ratio. This means that for every one monatomic ion from group 1a, two sulfate ions are needed to form a neutral compound.
What is a monatomic ion has an oxidation number?
A monatomic ion is an ion consisting of a single atom with a positive or negative charge. The oxidation number of a monatomic ion is equal to the charge of the ion.
Is potassium iodide a poly atomic ion?
No, potassium iodide is a compound composed of the monatomic ion K+ (potassium cation) and the monatomic ion I- (iodide anion). It is not a polyatomic ion.

Is magnessium a polyatonic ion?
No, magnesium is a monatomic ion with a 2+ charge.
Is sulfur hexafluoride a monatomic ion?
Sulfur hexafluoride is not a monatomic ion but in fact a molecular compound.
How does the oxidation number of a monatomic ion compare to its charge?
The oxidation number of a monatomic ion equals its charge. For example, the oxidation number of a sodium ion (Na+) is +1, which matches its charge of +1.

Which polyatomic ion forms a neutral compound when combined with a group 1a monatomic ion in a 1 2 ratio?
The sulfate ion (SO4^2-) forms a neutral compound when combined with a group 1a monatomic ion in a 1:2 ratio. This means that for every one monatomic ion from group 1a, two sulfate ions are needed to form a neutral compound.
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.
