What is a Compound? - A compound is a chemical substance can be broken down into two or more simpler substances. A chemical element that makeup compounds by combining with each other elements in definite proportions. Learn about Elements and Compounds Examples Here.
A compound consists of two or more elements chemically bonded in a fixed ratio. All compounds are examples of molecules, but molecules also include substances consisting of only one element, chemically bonded to itself.
Elements, Molecules, and Compounds. An element consists of only one type of atom. A molecule is composed of two or more atoms joined together by chemical bonds. Some molecules are examples of elements, such as H 2, N 2, and O 3. A compound is a type of molecule consisting of two or more different atoms joined by chemical bonds. All compounds ...
The difference between an element and a compound is that an element is a substance made of same type of atoms, whereas a compound is made of different elements in definite proportions. Examples of elements include iron, copper, hydrogen and oxygen.
Chemical compound, any substance composed of identical molecules consisting of atoms of two or more chemical elements. All the matter in the universe is composed of the atoms of more than 100 different chemical elements, which are found both in pure form and combined in chemical compounds.
A compound is a pure substance that is made from more than one element. In a compound, elements are chemically bonded together, which makes it very difficult to separate them.
A compound is a substance that contains two or more elements chemically combined in a fixed proportion. The elements carbon and hydrogen combine to form many different compounds. One of the simplest is called methane, in which there are always four times as many hydrogen particles as carbon particles.
Elements. An element is the simplest form of matter that has a unique set of properties. Examples of well-known elements include oxygen, iron, and gold (see below). Elements cannot be broken down into a simpler substance. Likewise, one element cannot be chemically converted into a different element. Chemical elements are the simplest of substances.
Water is an example of a compound, a mixture of two or more elements, and is created when two hydrogen atoms bond to an oxygen atom. Use these resources to examine the properties and uses of elements and compounds.
A pure substance made up of two or more elements chemically combined. There is an unlimited number of compounds. Compounds cannot be separated into their elements by physical means. E.g. copper (II) sulfate (CuSO 4), calcium carbonate (CaCO 3), carbon dioxide (CO 2)
