What is a substance composed of two or more different atoms chemically bonded to one another?
A chemical compound is a substance composed of two or more different elements chemically bonded together in a fixed proportion by mass. When a compound is formed from its components, a chemical change takes place through chemical reactions.
What is a substance formed when two or more elements are chemically joined?
Two or more elements combined into one substance through a chemical reaction, such as water, form a chemical compound. All compounds are substances, but not all substances are compounds.
What is a substance composed of two or more elements combined chemically in a fixed proportion by mass?
A compound is a substance that contains two or more elements chemically combined in a fixed proportion. The elements carbon and hydrogen combine to form many different compounds.
Which type of matter is composed of two or more?
compound
compound: A substance made from two or more elements. Consists of a fixed ratio of chemically bonded atoms.
Is composed of two or more elements?
Elements can be chemically combined into compounds, therefore, a compound consists of two or more elements combined, in definite proportions, by chemical means. Compounds may be formed by combining atoms of their constituent elements by ionic bonds or by covalent bonds.
Which type of matter is composed of two or more different elements that are chemically combined in a different ratio?
Elements can be chemically combined into compounds, therefore, a compound consists of two or more elements combined, in definite proportions, by chemical means. Compounds may be formed by combining atoms of their constituent elements by ionic bonds or by covalent bonds.
When two or more substances combined but each keeps its own properties?
A mixture is a physical blend of two or more components, each of which retains its own identity and properties in the mixture.
What is composed of two or more atoms held together by covalent bonds?
The group of atoms held together by covalent bonds is called a molecule.
Are composed of two or more different elements?
Compounds are made up of two or more elements combined in definite quantities and in definite proportions by chemical bonds. Substances are pure forms of matter that cannot be separated or purified further by physical means; include compounds and elements.
Are substances composed of two or more elements so they contain two or more kinds of atoms?
chemical compound, any substance composed of identical molecules consisting of atoms of two or more chemical elements. All the matter in the universe is composed of the atoms of more than 100 different chemical elements, which are found both in pure form and combined in chemical compounds.
What is held together by covalent bonds?
A covalent bond happens when the positive nuclei from two different atoms are held together by their common attraction for the shared pair of electrons held between them. Atoms that share pairs of electrons form molecules. A molecule is a group of atoms held together by covalent bonds.
