Differentiate between the following.
Elements and compounds
Difference Between Element and Compound
Sl. No. | Differentiating Property | Element | Compound |
---|---|---|---|
1 | Definition | 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. |
2 | Total Numbers | There are nearly 118 elements (at present) of which nearly 94 occur naturally on Earth. | Compounds are almost endless. |
3 | Types | Elements are classified as either metals, nonmetals or metalloids. | Compounds are classified according to their bonds which can be ionic, molecular or metallic. |
4 | Examples | Some of the examples of elements are Iron, Copper, Gold, etc. | A few examples of compounds are NaOH, NaCl, etc. |
5 | Representation | Elements are represented by symbols and numbers. For example, Sodium is represented by Na. | Compounds are represented by their chemical formula. For example, salt is represented by the formula NaCl. |
6 | Distinguished By | Elements can be distinguished by their atomic number. | Distinguished by their fixed ratio of different elements (arranged in a defined manner). |
7 | Composition and Property | As only one type of atoms makes up an element, all the properties of that atom are represented by its atom. | In the case of compounds, the same type of molecules makes up the compound. |
8 | Ability to Breakdown | Elements cannot be broken down by chemical reactions. | Compounds can be easily separated into simpler substances by chemical reactions. |
