What is Air Pollution-Types, Causes, Sources- Effects, Prevention, Control, Reduce

Air pollution means degradation of the air quality harmfully affecting the living organisms as well as certain objects. Environmental is the branch of science which deals the chemical changes in the environment. It includes our surroundings such as air, water, soil, forests, sunlight etc. Broadly speaking the environment has three main components. These are : (i) …

f block elements | lanthanides and actinides

Chemistry, D and F Block

The elements constituting the f block are those in which the 4f and 5f orbitally progressively filled.These elements are the member of group 3.The f block elements are also termed as inner transition elements.It is because literally speaking they constitute transition series within transition series (d-block elements). In addition to incomplete d-subshell, their f-subshell is also …

Periodic Table

Chemistry, periodic table

Understanding Periodic Table: A shopkeeper dealing in different items say stationary, cosmetics, confectionery, etc. place things of one type at one place. In the library, books on one subject are placed in one almirah. This is done for convenience and to make things easy and simple. Similarly, a total of 118 natural and synthetic elements are …

Properties of transition metals | d block Element

Chemistry, D and F Block

Properties of transition metals (d block elements) are transitional between the highly reactive metallic elements of s- block (which form ionic compounds) and the elements of p block (which are largely covalent). The d block is present in the centre of the periodic table and the elements are known as transition elements. There are four …

Van der Waals Equation

Chemistry, Van der Waals Equation

Van der Waal (1873) suggested two corrections in an ideal gas equation(PV = nRT) so that it can also explain the behavior of real gases. Hence the equation obtained by applying the two corrections to the usual gas equation is known as Van der Waals equation. Need of Van der Waals Equation Real gases deviate …

Electronegativity Chart With Values

Chemistry, periodic table

At the end of the article, you will able to describe why the electronegativity chart has a variation in values. Let’s get started. The tendency of an atom in a compound or molecule to attract the shared electrons towards itself is called as electronegativity of the atom. Electronegativity and electron-affinity both are measured as the …

Atomic Radius

Atoms, Chemistry

Theoretically, an electron, at one time, may be very close to the nucleus while at other time it may be far away from the nucleus. So, on certain facts, it is difficult to explain the exact atomic radius definition. Let’s explain it more clearly. Atomic Radius Definition Definition of Atomic radius – It is defined …
