Difference Between Mixtures and Compounds. The mixture contains two or more substances mixed, but neither chemically as well as not in inexact quantity while compound includes two or more elements combined chemically and in a fixed ratio. ... Even matter can be classified into two classes, mixtures, and the pure substances ...

Compounds: • A pure substance containing two or more kinds of_atoms • The atoms are chemically combined in some way. Often times (but not always) they come together to form groups of atoms called molecules. ... Mixtures can be separated into their components by chemical or physical means.

A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons. An element is a substance that is made entirely from one type of atom. ... A compound is a substance made from two or more different elements that have been chemically joined.

1 Answer. A compound is a pure substance that is composed of elements chemically bonded in definite proportions. A compound can be broken down into simpler substances only by chemical reactions, such as electrolysis. A solution is a homogeneous mixture, meaning that it is the same throughout.

Elements and compounds are both examples of pure substances. A substance that cannot be broken down into chemically simpler components is an element.

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.

A compound is a substance formed when two or more elements are chemically joined. Water, salt, and sugar are examples of compounds. When the elements are joined, the atoms lose their individual properties and have different properties from the elements they are composed of.

A compound contains atoms of different elements chemically combined together in a fixed ratio. An element is a pure chemical substance made of same type of atom. ... Elements contain only one type of atom.

A compound consists of the atoms of two or more elements that are chemically joined to each other. Since the atoms are always joined in the same ratio, the composition of a compound is always the same. ... A mixture consists of two or more substances that are physically intermingled in different proportions.

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. There are nearly 118 elements (at present) of which nearly 94 occur naturally on Earth.

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.

Substances are made of elements. Compounds, or "compound substances", are made of different elements (types of atoms). Elementary substances are made of a single element (one type of atoms). ... Ont the other hand, a compound, is a certain kind of substance, constituted by a regular combination of different elements.

Compound are substances which can be formed by chemically combining two or more elements. Mixtures are substances that are formed by physically mixing two or more substances. Compounds can be of three types, which are: covalent compounds, metallic compounds and ionic compounds.

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.
