The chemical formula of the compound shows the ratio of the atoms of elements in a compound. This must not be confused with the ratio of their masses.
The fixed ratio of a chemical compound is known as its stoichiometry. This ratio is the quantitative relationship between the number of atoms of each element in the compound, as expressed by the compound's chemical formula.
A compound.
The answer depends on the compound.
This ratio is different for each compound; for the oxide P4O10 the ratio is 2/5.
The ratio of phosphorus atoms to oxygen atoms in a compound can vary depending on the specific compound. For example, in phosphorus pentoxide (P4O10), the ratio is 4:10.
A compound has a definite ratio of components.
The ratio of hydrogen to oxygen in water is 2:1.
To determine the ratio of ions in a compound, you first need to identify the chemical formula of the compound. The subscripts in the chemical formula indicate the ratio of ions in the compound. For example, in NaCl (sodium chloride), the ratio of sodium ions to chloride ions is 1:1.
The proportions of elements in a compound are fixed, meaning that a specific compound will always have the same ratio of elements by mass. This fixed ratio is determined by the chemical formula of the compound.
The smallest whole number ratio of elements in an ionic or covalent compound is known as the empirical formula. It represents the simplest ratio of atoms of each element in a compound.
The simplest ratio of ions in an ionic compound is called the formula unit. It represents the ratio of positive and negative ions that are present in the compound in the smallest whole number ratio possible.
