No
Sulfur commonly forms a -2 charge as a simple monatomic ion by gaining two electrons to achieve a stable electron configuration.
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.
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.
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.
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.
Sulfur hexafluoride is not a monatomic ion but in fact a molecular compound.
Yes, sulfur hexafluoride (SF6) is an example of a polyatomic molecule because it consists of more than two atoms bonded together (one sulfur atom and six fluorine atoms).
Sulfur commonly forms a -2 charge as a simple monatomic ion by gaining two electrons to achieve a stable electron configuration.
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.
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.

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.
Yes. Mg2+ is a monatomic ion, but SO42- is a polyatomic ion composed of two elements, sulfur and oxygen.
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.
This ion is the hydrogen cation.
No, magnesium is a monatomic ion with a 2+ charge.
