    What formula is a polyatomic ion?
    A polyatomic ion is not a formula, but rather a group of atoms that are covalently bonded and carry an overall positive or negative charge .

    Aquí hay un desglose de los componentes clave:

    * Group of Atoms: Multiple atoms are bonded together, like a small molecule.

    * Covalently Bonded: The atoms share electrons, not transfer them.

    * Cargo general: The entire group has a net positive or negative charge due to a gain or loss of electrons.

    Examples of Polyatomic Ions:

    * Nitrate (NO₃⁻) :One nitrogen atom and three oxygen atoms with a -1 charge.

    * Ammonium (NH₄⁺) :One nitrogen atom and four hydrogen atoms with a +1 charge.

    * sulfato (so₄²⁻) :One sulfur atom and four oxygen atoms with a -2 charge.

    Formula Writing:

    The formula of a polyatomic ion is written as the symbol of the element with its subscript followed by the charge in superscript.

    Ejemplo:

    * Nitrate (NO₃⁻): This formula indicates one nitrogen atom (N) and three oxygen atoms (O₃) with a -1 charge.

    Remember:

    * Polyatomic ions are treated as a single unit in chemical reactions and formulas.

    * Their charges must balance with other ions to form neutral compounds.
