The Law of Definite Proportions says that a given chemical compound always contains the same proportion by mass of its constituent elements. This is NOT the same as saying that elements always combine in a specific ratio, because they can combine in different ratios in different compounds. An example of this might be copper oxide which can be CuO or Cu2O, showing a different ratio of copper to oxygen. So, the answer to the question, as asked, is no, elements do not always combine in specific ratios.
Yes, elements combine in specific ratios to form compounds due to the laws of chemistry, such as the Law of Definite Proportions, which states that a compound always contains the same elements in the same proportion by mass. This allows for the predictable behavior of chemical reactions and the formation of well-defined substances.
Elements combine in definite, but variable proportions, depending on their particular structure and isotope.
Yes, otherwise it would not be that elemnt
Some elements can have different isotopes.
See the link bellow for the Law of definite proportions. But be sure that this law is not generally valid.

Do elements that combine in changing ratios form mixtures?
When elements combine in changing ratios, they form compounds rather than mixtures. Mixtures are made up of different substances that are not chemically bonded together, while compounds are formed by chemical bonding between elements in specific ratios.
What do compounds always contain in exact ratios?
Compounds always contain elements in exact ratios, based on the chemical formula of the compound. This means that the elements are present in specific and consistent proportions in the compound.
Do elements combine to make compounds?
Yes, elements combine in specific ratios to form compounds. A compound is a substance made up of two or more different elements chemically bonded together. The chemical bonds between elements in compounds are formed through interactions at the atomic level.
What Elements combine in fixed mass ratios to form compounds This must mean that elements?
In chemical compounds, elements combine in fixed ratios by mass to form stable, distinct substances. This observation is summarized in the law of definite proportions, which states that a compound is always composed of the same elements in the same proportions by mass. This principle demonstrates the predictable and reproducible nature of chemical reactions.
Are iron and silicon chemical compounds?
Iron and silicon are elements, not chemical compounds. Chemical compounds are formed when elements combine in specific ratios through chemical bonds.
Do elements that combine in changing ratios form mixtures?
When elements combine in changing ratios, they form compounds rather than mixtures. Mixtures are made up of different substances that are not chemically bonded together, while compounds are formed by chemical bonding between elements in specific ratios.
What is formed when two or more elements combine?
When two or more elements combine, they form a compound. Compounds are composed of atoms of different elements bonded together in specific ratios.
What do compounds always contain in exact ratios?
Compounds always contain elements in exact ratios, based on the chemical formula of the compound. This means that the elements are present in specific and consistent proportions in the compound.
What type of matter is made of elements in a specific ratio that is always the same?
Elements combined in specific ratios form compounds.
What do you get with changing ratios that combine in elements?
In this mode different compounds are obtained.
How did dalton explain the formation of compounds?
Dalton proposed that elements combine in simple whole number ratios to form compounds, based on his atomic theory. He suggested that atoms of different elements combine in specific ratios to form compounds, where each compound has a unique composition. This explanation laid the foundation for understanding chemical reactions and the formation of compounds.
What are compounds composed of?
Compounds are composed of two or more different elements that are chemically bonded together. These elements combine in fixed ratios to form specific compounds with unique chemical and physical properties.
When two or more elements combine chemically it is called?
When two or more elements combine chemically, it is called a chemical compound. In a chemical compound, the elements are bonded together in specific ratios to form a new substance with unique properties.
Elements combine in a specific proportion?
Chemical elements combine in specific ratios to form compounds. This is governed by the principles of stoichiometry and reflects the fixed ratio of atoms in a compound's chemical formula. The specific proportion of elements in a compound determines its properties and behavior.
Do elements combine to make compounds?
Yes, elements combine in specific ratios to form compounds. A compound is a substance made up of two or more different elements chemically bonded together. The chemical bonds between elements in compounds are formed through interactions at the atomic level.
What are compounds made up of?
Compounds are made up of two or more different elements that are chemically bonded together. These elements combine in specific ratios to form compounds with unique properties.
What Elements combine in fixed mass ratios to form compounds This must mean that elements?
In chemical compounds, elements combine in fixed ratios by mass to form stable, distinct substances. This observation is summarized in the law of definite proportions, which states that a compound is always composed of the same elements in the same proportions by mass. This principle demonstrates the predictable and reproducible nature of chemical reactions.
