iron | Element, Occurrence, & Compounds | Britannica Occurrence, uses, and properties. Iron makes up 5 percent of Earth’s crust and is second in abundance to aluminum among the metals and fourth in abundance behind oxygen, silicon, and aluminum among the elements.Iron, which is the chief constituent of Earth’s core, is the most abundant element in Earth as a whole (about 35 percent) and is relatively plentiful in the Sun and other stars. What is compound? - Definition from WhatIs.com 1) In chemistry, a compound is a substance that results from a combination of two or more different chemical element s, in such a way that the atom s of the different elements are held together by chemical bonds that are difficult to break. These bonds form as a result of the sharing or exchange of electron s among the atoms. The smallest unbreakable unit of a compound is called a molecule.
7 Oct 2014 An element is a single type of atom, while a compound consists of two or more types of atoms. Elements cannot be further divided into smaller
Note that an element: consists of only one kind of atom, cannot be broken down into a simpler type of matter by either physical or chemical means, and; can exist as either atoms (e.g. argon) or molecules (e.g., nitrogen). A molecule consists of two or more atoms of the same element, or different elements, that are chemically bound together Difference Between Element and Compound – Difference Wiki Element vs. Compound. The element is the chemical substance that is made up of similar kinds of atoms joined. It can be in any state of matter and form.
