It stands for acetate.
[CH3CO0]- lets you know what the molecule looks like.
It will be C with 3H attached to it one one side, than another C with 2O attached to it on the other side (one O will be double bond).
3H-C-C-2O (with one O double bond)
C2H2O2 just tells you what elements and how many of each element you get in the formula.
A polyatomic formula is a chemical formula that represents a polyatomic ion, which is a group of covalently bonded atoms that carries a net charge. These formulas are used to describe compounds that contain these complex ions, such as sulfate (SO4^2-) or ammonium (NH4+).
No, oxide is just an oxygen ion. The formula is just O(-2 charge), hence not a polyatomic ion. Hydoxide on the other hand is a polyatomic ion, formula being OH(-1 charge)
To indicate that a polyatomic group is present more than once in an ionic formula, you enclose the group in parentheses with a subscript outside the parentheses representing the number of times it occurs. For example, in calcium nitrate (Ca(NO3)2), the polyatomic nitrate group (NO3) is present two times.
One reason is that the composition of a polyatomic ion is fixed, just as that of a compound is fixed. If more than one polyatomic ion is present in an ionic compound, the use of parentheses allows a subscript to be used after the right parenthesis to designate the number of ions just as such subscript is used to designate the number of atoms in a compound.
Parentheses are used in the formula of an ionic compound when there is more than one polyatomic ion in the formula. They help indicate the correct ratio of ions in the compound. For example, in calcium nitrate (Ca(NO3)2), parentheses are used to show that there are two nitrate ions for every one calcium ion.
Acetate ion is CH3C00-, C2H3O2-. It is the conjugate base of acetic acid, CH3COOH

More than one polyatomic ion should be indicated in a chemical formula by putting parentheses around the atoms in the ions and then adding a subscript.

Ca(CH3COO)2 is the chemical formula of calcium acetate.

Ions made up of more than one atom are called polyatomic ions.
The polyatomic ion in chloric acid is the chlorate ion, which has a chemical formula of ClO3-. It consists of one chlorine atom bonded to three oxygen atoms. Chloric acid is derived from this chlorate ion in the form of HClO3.
