Physical Properties of Metals And Non-Metals Definitions, Equations and Examples
Physical Properties of Metals And Non-Metals:
On the basis of their properties, all the elements can be divided into two main groups: metals and non-metals, Apart from metals and non-metals, there are some elements that show characteristics of both meta…
Chemical Properties of Metals and Non-Metals Definitions, Equations and Examples
Chemical Properties of Metals and Non-Metals:
Metals are electropositive in nature as they lose electrons and form positive ions.
K → K+ + e–
Ca → Ca2++ 2e–
Non-metals are electronegative in nature as they accept electrons and form negative ions.
Cl + e…
Reaction Between Metals and Non-Metals Definitions, Equations and Examples
Electronic Configuration of Noble Elements:
Noble gases have a completely filled valence shell and hence are chemically inert. The usual number of valence electrons in the atom of noble gases is 8 except helium in which it is 2.
Cause of Chemical Reacti…
Occurrence And Extraction of Metals Definitions, Equations and Examples
Occurrence And Extraction of Metals:
A major source of metals is the earth’s crust. Soluble salts of certain metals such as sodium chloride, magnesium chloride, etc., are also found in seawater. Minerals: The inorganic elements or compounds which occur …
Corrosion of Metals Definitions, Equations and Examples
Corrosion of Metals:
The phenomenon of a surface of metal being attacked by air, water or any other substance around it is known as corrosion and the metal being attacked is said to corrode.
Examples of corrosion:
When iron is exposed to moist air for …
Covalent Bonding in Carbon Definitions, Equations and Examples
Covalent Bonding in Carbon:
The amount of carbon present in the earth’s crust and in the atmosphere is very less. The earth’s crust has only 0.02% carbon in the form of minerals (like carbonates, hydrogencarbonates,coal and petroleum) and the atmosphere…
Versatile Nature of Carbon Definitions, Equations and Examples
Versatile Nature of Carbon
It is estimated that there are about three million carbon compounds whose formulae are known to chemists which is much greater than the compounds formed by all the other elements put together.
The factors due to which this is …
Hydrocarbons Definitions, Equations and Examples
Hydrocarbons
The compounds made up of hydrogen and carbon only are called hydrocarbons. These are the simplest organic compounds and all other compounds are considered to be derived from them by the replacement of one or more hydrogen atoms by other ato…
Functional Groups Definitions, Equations and Examples
Functional Groups
A functional group in an organic compound is an atom or a group of atoms bonded together in a unique fashion, which is usually the site of chemical reactivity in an organic molecule.
If in a hydrocarbon chain, one or more hydrogen atom…
Homologous Series Definitions, Equations and Examples
Homologous Series
A homologous series is a group of organic compounds having similar structures and similar chemical properties in which the successive compounds differ by CH2 group.
Characteristics of Homologous Series
All the members of a homologous …
