Two or more substances mixed together but not chemically combined form a mixture.
A substance composed of more than one type of atom, chemically combined, is called a compound.
elements are denoted by the symbol of their formula/name, only. Fe = iron, S = sulfur, no other element is involved when something is a pure element. diatomic gases, O2, N2, etc. are elements compounds have 2 or more elements in the formula mixtures are when 2 or more substances are placed together but they are not bound to each other if the compound has (aq) after the symbols, this means that the compund is in aqueous conditions and this is a solution, which is a mixture. i copied and pasted this from yahoo so please don't hate!

CH4 is a compound. It is the chemical formula for methane, which is a simple molecular compound consisting of one carbon atom and four hydrogen atoms bonded together. A heterogeneous mixture would involve different substances not chemically bonded like in a compound.
Two or more substances mixed together but not chemically combined form a mixture.
A mixture is a combination of two or more substances that are not chemically bonded. An example of a mixture is a solution of salt and water where the salt dissolves in the water but does not chemically combine with it.
2 different Elements chemically bonded together is called a Compound.
In chemistry, a compound is a substance made up of two or more different elements that are chemically bonded together. These elements combine in fixed ratios to form a unique substance with distinct properties. Examples of compounds include water (H2O) and sodium chloride (NaCl).
By definition -- that's how you define a molecule. Sort of like asking why are those things on my feet called socks? Because when we put cloth of our feet, we tend to call them socks. Could be a blanket, of course. Once you say "Chemically bonded" atoms, you are stuck with the name "molecule."
A compound refers to two or more elements chemically bonded together in a fixed proportion. This fixed proportion is represented by a chemical formula that shows the types and ratios of atoms present in the compound.
of Compound
Two or more atoms of different elements joined together form a compound. If it is a metal and non-metal (for example sodium and chlorine), they are ionically bonded. If it is two non-metals (for example methane is carbon and hydrogen), they are covalently bonded.
A substance composed of more than one type of atom, chemically combined, is called a compound.
It depends on the substance your are talking about. It could be a compound, mixture, or substance; depending on the substance. If it is an element off the periodic table, it is an element. If it is two elements chemmically combined, it is a compound. If it is two elements that are not chemically combined, it is a mixture.
Mixture - A physical blend of two or more substances that are NOT chemically combined. Compound - A substance that contains two or more elements CHEMICALLY combined in a fixed proportion. Compound is chemically combined, mixture is not chemically combined. Cake would be a compound because all of the ingredients are together to make batter you cannot see the individual components (eggs, flour, sugar, etc). Trail mix would be a mixture because you can see every individual item (m&m, peanuts, raisins, etc.)
