Water is made up of two different elements, 2 hydrogens and 1 oxygen, so H2O is a compound. Two oxygen atoms (O2) are two elements, but they are the same element, so O2 is a molecule. Iron oxide (Fe2O3), or rust, is made up of two different elements, 2 irons and 3 oxygens...

Rust is another name for iron oxide, which occurs when iron or an alloy that contains iron, like steel, is exposed tooxygenand moisture for a long period of time. Over time, the oxygen combines with the metal at an atomic level, forming a new compound called an oxide and weakening the...
Which is larger: 1/3 or 1/5? Explain. What is radiology? Given that A=2 - log(%T), if A=1.59, then what is %T? What are the formal charges in O_3? What is corrosion? What is rust? Why do we define (1/X)(d^2/dx^2)X as (-2mE_x/h^2) and not simply as E?
The term 'oxidation' derives from the ancient observation of rust (oxide) formation. Early chemists could determine an increase in the weight of a metal as it a
(chemistry) A reaction in which the atoms of an element lose electrons and the oxidation state of the element increases. Oxidation The act or process of oxidizing, or the state or result of being oxidized. Oxidation The process of oxidizing; the addition of oxygen to a compound with a loss...
As an example, consider rust formation. When rust forms, the metal iron reacts with oxygen in the air to form a new compound, iron oxide (rust). This chemical reaction may be expressed by the following unbalanced chemical equation, which may be written either using words or using the chemi...
