تعريف isomer في الإنجليزية الإنجليزية القاموس.

Any of two or more atomic nuclei with the same mass number and atomic number but with different radioactive properties

Any of two or more compounds with the same molecular formula but with different structure

One of a group of substances having the same combination of elements, but these elements are arranged spatially in different ways

chemical compound that has the same number, and kinds of atoms as another compound, but a different structural arrangement of the atoms

When two molecules have the same elemental composition but different structures, they are said to be isomers

molecule having the same molecular formula as another molecule, but having a different structure and, therefore, different properties As the carbon atoms in a molecule increase, the number of possible combinations, or isomers, increases sharply For example, octane, an 8-carbon-atom molecule, has 18 isomers; decane, a 10-carbon-atom molecule, has 75 isomers

Any of two or more nuclei with the same mass number and atomic number but with different radioactive properties

One of several nuclides having the same number of neutrons and protons but capable of existing, for a measurable time, in different quantum states with different energies and radioactive properties Commonly, the isomer of higher energy decays to one with lower energy by the process of isomeric transition

One of several nuclides with the same number of neutrons and protons capable of existing for a measurable time in different nuclear energy states

compounds that have the same molecular formulas but different structural formulas(also called constitutional isomers)

One polyhedron is an isomer of another (ie they are isomeric) if they have the same number of faces of each kind, the same number of vertices, and the same number of edges, but they are not isomorphic Also, the number of vertices of each type must match, eg one type of vertex may be surrounded by three squares and one triangle For example the rhombicuboctahedron and its pseudo version

Organic compounds of identical composition and molecular weight, but having a different molecular structure

A compound with the same atomic composition and molecular weight as another compound but differing in molecular structure and chemical or physical properties For example, graphite (pencil lead) and diamond are isomers of carbon Both are composed of pure carbon, but exhibit very different physical properties

One of two or more substances with identical molecular formulas but different configurations, differing only in the arrangement of their component atoms. It usually refers to stereoisomers (rather than constitutional isomers or tautomers; see isomerism, tautomerism), of which there are two types. Optical isomers, or enantiomers (see optical activity), occur in mirror-image pairs. Geometric isomers are often the result of rigidity in the molecular structure; in organic compounds, this is usually due to a double bond (see bonding) or a ring structure. In the case of a double bond between two carbon atoms, if each has two other groups bonded to it and all are rigidly in the same plane, the corresponding groups can be on the same side (cis) of the CC bond or across the CC bond (trans) from each other. An analogous distinction can be made for ring structures that are all in a plane, between isomers whose substituent groups are on the same side and isomers whose substituent groups are on both sides of the plane. Diastereomers that are not enantiomers also fall into this category. Most cis-trans isomers are organic compounds

Compounds that have the same molecular formula, but have different structures

a compound that exists in forms having different arrangements of atoms but the same molecular weight

In chemistry, isomers are the compounds that have identical molecular formulas but differ in the nature or sequence of bonding of their atoms or in the arrangement of their atoms in space In physics, isomers are the nuclei of the same atomic number Z and mass number A but in different energy states

Having the same number of atoms of each element as another molecule Back to top L

Nuclides with the same number of neutrons and protons in different states of excitation

A body or compound which is isomeric with another body or compound; a member of an isomeric series

A molecule which has an identical molecular formula to another molecule, but has a different structure

Molecules with identical molecular formulas but different structural formulas [Fred Senese, General Chemistry Glossary, Frostburg State University, 2001] http: //antoine frostburg edu/chem/senese/101/glossary shtml

{i} chemical compound which has the same number and kind of atoms as another but differs in structural arrangement (Chemistry)
