what is the difference between elements and compounds examples?

An element is a substance that is made entirely from one type of atom. For example, the element hydrogen is made from atoms containing just one proton and one electron. ... A compound is a substance made from two or more different elements that have been chemically joined.

What is the difference in composition between most minerals and a pure element? The difference is the most minerals are compounds and pure elements are pure. ... Minerals can form by crystallization of magma and crystallization of minerals.

Elements are pure substances which are composed of only one type of atom. Compound are substances which are formed by two or more different types of elements that are united chemically in fixed proportions.

Ionic compounds are compounds whereas metals are elements. Ionic compounds are electrolytes whereas metals are conductors. Ionic compounds are brittle whereas metals are malleable and ductile. Metals are sonorous and are shiny whereas ionic compounds are not.

Compounds contain two or more atoms and are held together by ionic bonds, whereas molecules are held together by covalent bonds. The atoms within a compound also must be different from eachother, whereas a molecule can consist of only one element.

An element is a pure substance that cannot be broken down into different substances. In the case of water, the elements are hydrogen and oxygen. ... A compound is defined as a pure substance: formed when two or more elements chemically combine to form bonds between their atoms.
846306
Chemical compounds are pure substances which contain two or more chemical elements. ... Different types of chemical bonds include ionic bonds (which are found in salts), metallic bonds (which are found in metals), and covalent bonds (which are found in molecular compounds).

There are two basic types of compounds. They are distinguished by by the manner in which the atoms bind to one another in the compound. These two types are called "molecular" compounds and "salts" (or equivalently "ionic" compounds):

1). All compounds are molecules, but not all molecules are compounds (if they happen to have atoms of the same element). Diatomic molecules are molecules composed of only two atoms of either the same or different elements. ... These are the seven diatomic elements on the periodic table.

Compounds and mixtures are sometimes used as synonyms by laypersons. While the terms do overlap, they're technically not the same. Compounds are two or more elements chemically combined in definite proportions by weight. Mixtures are two or more substances not chemically combined.

Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass. Compounds can be decomposed into simpler constituents using chemical reactions.
310740
The only difference between a molecule of a compound and a molecule of an element is that in a molecule of an element, all the atoms are the same. For example, in a molecule of water (a compound), there is one oxygen atom and two hydrogen atoms. But in a molecule of oxygen (an element), both of the atoms are oxygen.

Ionic compounds are compounds consisting of ions. Two-element compounds are usually ionic when one element is a metal and the other is a non-metal. Examples include: sodium chloride: NaCl, with Na+ and Cl- ions.
902346
Compound are substances which are formed by chemically combining two or more elements. Mixtures are substances that are formed by physically mixing two or more substances.
600454
An atomic element is an element which exists independently as atoms and can still react with other elements forming a compound. ... An element is the single, smallest entity of a pure substance which can take part in chemical reaction. A molecular compound is a compound which consists of molecules, as the name implies.

['an element contains just one type of atom.', 'a compound contains two or more types of atom joined together.', 'a mixture contains two or more different substances that are not joined together.', 'the different substances in a mixture can be elements or compounds.']

Element: ... A compound is a pure substance made up of two or more elements chemically combined in a fixed proportion by mass. Mixture: An impure substance or mixture is a substance that contains two or more pure substances physically mixtures in any proportion.
