In chemistry, a compound is a substance made of two or more elements chemically bonded to each other in a fixed ratio. The chemical bonds between atoms of elements involve a transfer or sharing of valence of electrons. This give a compound different properties from its elements.
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.
A chemical compound is a chemical substance composed of many identical molecules (or molecular entities) containing atoms from more than one chemical element held together by chemical bonds. A molecule consisting of atoms of only one element is therefore not a compound.
The molecular formula of a covalent compound gives the types and numbers of atoms present. Compounds that contain predominantly carbon and hydrogen are called organic compounds, whereas compounds that consist primarily of elements other than carbon and hydrogen are inorganic compounds.
What is a Compound? - A compound is a chemical substance can be broken down into two or more simpler substances. A chemical element that makeup compounds by combining with each other elements in definite proportions. Learn about Elements and Compounds Examples Here.
A compound is a chemical species that is formed when two or more atoms join together chemically, with covalent or ionic bonds. Compounds may be categorized according to the type of chemical bonds holding the atoms together: Molecules are held together by covalent bonds. Ionic compounds are held together by ionic bonds.
A compound is a pure substance that is made from more than one element. In a compound, elements are chemically bonded together, which makes it very difficult to separate them.
Definition of compound: In chemistry, a compound is a pure substance that is composed of two, or more different elements, chemically combined with one another in a definite ratio. In other words, a compound is a unique substance that can be broken down (or decomposed) into simpler substances by some suitable chemical reaction or change.
Course: High school chemistry > Unit 3. Lesson 4: Covalent bonds. Covalent bonds. Lewis diagrams for molecules. Molecules, salts, compounds, and chemicals: What's the difference? Understand: covalent bonds. Apply: predicting covalent bonds. Apply: covalent bonds and molecules.
Compounds occur when two or more atoms combine into a pure substance. These can be broken down into their constituent atoms. In chemical reactions the atoms of the reactants interact to form new substances. The reacting species are called reactants, and those produced are products.
