This is the percentage of the element in the compound.
If it is a molecular compound, the formula indicates the numbers of atoms of each element in one molecule of the compound. If it's an ionic compound, the formula unit indicates the lowest whole number ratio of ions in the compound.
It is a formula unit.
the lowest whole number ratio of elements in a compound A+
An empirical formula gives this information indirectly by specifying the ratios of numbers of atoms of each element in a compound to the total number of atoms in a compound. These ratios can then be mathematically converted into the mass ratios specified in the question by using the known atomic weights of each element present: The mass ratio of element "Q" to element "R" is equal to the number ratio multiplied by the ratio of the atomic weight of element Q to that of element R. For example, the number ratio of hydrogen to oxygen in water is 2, but the mass ratio is 2(1.008/15.999) = 0.1260.
The lowest whole number ratio of positive to negative ions in the compound.
A formula unit shows the lowest ratio of ions that combine to make this compound.
The compound of copper and chlorine with the lowest atomic ratio of copper to chlorine is CuCl2.
Based on % composition, one can determine the moles of each element in, say, 100 grams of compound. Then, one can see the mole ratio of all the elements in the compound, and adjust them so as to obtain whole numbers in the lowest possible ratio. This is then the empirical formula.
The simplest ratio of atoms of each element within a compound
its a compound. it consists of carbon and oxygen in a fixed ratio.
The ratio in mixtures can be varied, within reason, with little impact on the properties of the mixture. The ratio in compounds is fixed.
Copper chloride is a compound, with a fixed atomic ratio between copper and chlorine.
An empirical formula shows the simplest ratio of atoms between it's element in a compound. It indirectly shows a mass ratio between the elements and compound.

Carbon is a chemical element, not a compound.
Usually the lowest whole number ratio of ions in the compound, called the empirical formula or the formula unit.
an empirical formula For an ionic compound, the empirical formula is called a formula unit.
Salt is a molecular compound. It contains Na+ and Cl- ions in a 1:1 ratio.
The empirical formula of a chemica compound is the simplest positive integer ratio of atoms of each element present in a compound.
