How many atoms make up the oxlate ion?
C2O4=
2C atoms + 4 O atoms.
To determine the number of atoms in the oxalate ion (C₂O₄²⁻), we can use the subscripts in the chemical formula. The subscript next to each element tells us how many atoms of that element are present in the molecule or ion.
In the case of the oxalate ion, the formula C₂O₄ indicates that there are two carbon atoms (C₂) and four oxygen atoms (O₄). Thus, the oxalate ion is composed of 2 carbon atoms and 4 oxygen atoms.
Therefore, the number of atoms that make up the oxalate ion is 2 carbon atoms and 4 oxygen atoms.
