A material that contains three elements joined in a fixed proportion is a pure substance called a compound. It is not a mixture.
If a material contains three elements joined in a fixed proportion, then it is a compound. It can only be separated by a chemical reaction.
A substance made of two or more elements chemically combined in a specific proportion is called a compound. A substance composed of two or more elements combined chemically in a fixed proportion by mass is called a compound. A chemical compound can be held together by a covalent bond or an ionic bond.
Elements and compounds are called substance....subtances can be either elements or compound....an elementis a substance that cannot be separated into simpler substances by ordinary means...!!a compound is a pure substance that contains two or more elements combined in afixed proportion.......example of the formation of a comp. :1. Sodium plus chlorine --> sodium chloride
The special molecule that contains genetic material is called a chromosome.
These elements are called noncoductors.
It is called a compound
This is a chemical compound.
"In chemistry, the law of definite proportions and also the elements, sometimes called Proust's Law, states that a chemical compoundChemical_compoundalways contains exactly the same proportion of elementsChemical_elementby mass. An equivalent statement is the law of constant composition, which states that all samples of a given chemical compound have the same elemental composition." - Wikipedia

This is Dalton's Law of fixed proportions.
