Here in this topic we will discuss definition of molecule in chemistry, molecule examples and properties of molecules. “Smallest particle of elements or compounds which may survive solely is called Molecule.” Composition & Molecule example: It consist of, One atom of the element (monoatomic molecule) E.G., He, Ne, Xe etc. Two atoms of…
The most used definition of atom is as follows, “The smallest particle of an element, which may or may not have an independent existence but can take part in a chemical reaction is called atom.” Explanation of Define Atom: For example, the smallest particle of hydrogen, which does not exist independently is…
According to Greek philosophers, matter is composed of very small particles which cannot be further divided. DEMOCRITUS (460-370BC) named these particles as atoms derived from a Greek word “ATOMOS” which mean indivisible. The ideas of Greek philosophers were not experimental based. In the late 17th century, the quantitative analysis of many substances disclosed that they…
The most comprehensive Melting point Definition is, The temperature at which liquid & solid form of a substance co-exits in equilibrium under given pressure, is called Melting point. Normally standard pressure is taken as 1 atmosphere. In other way, we can also define melting point as, The temperature at which solid phase of a substance…
The famous philosopher of the 16th century, Sir Francis Bacon, defined science as a blessing that enriches human health and welfare with new products and methods.This laid foundation for importance of chemistry. The technology of the 20th century and the next century is a product of scientific discoveries. And most of these discoveries have left their mark…
Following are the main Branches of Chemistry. Organic Chemistry: “The branch of chemistry which deals with the compounds which have carbon as basic constituent elements attached with each other through catenation, is called organic Chemistry.” In other words, Organic chemistry is also called “carbon chemistry.” It is the sub-branch of chemistry science which is active in fields such…
