Solutions are dissolved in liquids. Elements are pure atoms of a single variety. Compounds are mixtures of different types of elements to make larger molecules. If it isn't a pure element and it's solid, the chances are that it's either one compound or a variety of compounds.
They are a "compound" of two elements fused together by a chemical reaction. The chemical make-up of water is two hydrogen atoms and one oxygen atom: H2O.
Molecules are the combination of two or more atoms which may exist free in gaseous form or in solutions, the ionic compounds are not the molecular compounds because their one unit can not exists freely but as the crystal lattice.
Oil is a mixture of compounds (2 or more elements bonded together), not an element itself, so it does not appear in the periodic table. Crude oil is a mixture of Hydrogen and Carbon compounds (hydrocarbons) of varying lengths, but with the general formula CnH2n+2, for example octane, C8H18. The different compounds within the oil are separated by fractional distillation before it is suitable for use.
The ancient Greek philosophers had talked about atoms, but Dalton's theory was different in that it had the weight of careful chemical measurements behind it. It wasn't just a philosophical statement that there are atoms because there must be atoms. His atomic theory had these fundamental points :Elements consist of tiny particles called atoms.Elements are pure because all atoms of an element are identical and that in particular they have the same mass.Elements differ from one another because atoms of each element are different from one another; in particular, they have different masses.Compounds consist of atoms of different elements combined together. Compounds are pure substances (remember they cannot be separated into elements by phase changes) because the atoms of the different elements are bonded to one another somehow, perhaps by hooks, and are not easily separated from one another.Compounds have constant composition because they contain a fixed ratio of atoms and each atom has its own characteristic weight, thus fixing the weight ratio of one element to the other.Chemical reactions involved the rearrangement of combinations of the atoms in a substance.Dalton's Atomic Theory had several main points, which are variously grouped into five statements :1) All matter is made of atoms.2) Atoms of a given element are identical in size, mass and chemical properties.3) Atoms of different elements have different masses and properties.4) Compounds are formed by a combination of two or more different kinds of atoms. The elements combine in simple, whole-number ratios.5) Atoms cannot be subdivided, created, or destroyed, but merely rearranged in their compounds with other elements. They can be combined, separated, or changed in the way in which they are arranged.
compounds are those elements put together
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 elements join together, they form compounds. Compounds are made up of two or more different elements that are chemically bonded together. This bonding can be either covalent (sharing electrons) or ionic (transferring electrons).
Compounds are chemical substances that is formed when two or more different types of elements join together.
Compounds include two or more different elements chemically bonded together. The elements are held together by chemical bonds which can be covalent or ionic. Examples of compounds include water (H2O) and sodium chloride (NaCl).
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.
In science, compounds are substances made up of two or more elements chemically bonded together in fixed proportions. These compounds have unique properties different from their component elements.
All compounds are molecules, but not all molecules are compounds. Compounds are substances made up of two or more different elements chemically bonded together, while molecules can be a single element or a combination of different elements bonded together.
Compounds are substances that consist of two or more substances bonded together. Examples include water and carbon dioxide. Compounds can only be separated into their component elements by chemical means.
compounds are two or more elements put together
Compounds are composed of two or more different elements chemically bonded together. The elements combine in specific ratios to form compounds with unique properties different from the properties of the individual elements.
Common compounds made up of two different elements include water (H2O), carbon dioxide (CO2), and salt (NaCl). Each of these compounds consists of atoms from two different elements chemically bonded together.
