TEXT A
INORGANIC CHEMISTRY
A branch of chemistry which deals with the study of elements in the periodic table and
their compounds, their physical and chemical properties is called inorganic chemistry.
Inorganic chemistry deals with all topics except a part of carbon chemistry, which is dealt
with under organic chemistry. Inorganic compounds are generally those that are not
biological, and characterized by not containing any hydrogen and carbon bonds. 
The term "organic" has traditionally referred only to animal or plant matter, so there is
a common misconception that organic chemistry always refers to life processes, or that
inorganic chemistry applies to everything that does not. This assumption is inaccurate. Many
chemical processes veer away from this line of thinking, and there are many chemical life
processes that depend on inorganic chemical processes.
There are exceptions to every rule. Although carbon is the main common element in
organic chemistry, inorganic chemical compounds can contain carbon, too. For example,
carbon monoxide and carbon dioxide both contain carbon, but are inorganic compounds.
Carbon dioxide, in particular, is also very important to chemical processes necessary for life,
especially plant life. The truth is that the lines between inorganic and organic chemistry are
often blurred.
Inorganic chemistry deals with the following topics:
Atomic Structure
The history of atomic structure is studied under inorganic
chemistry. Though atomic structure is studied under physical
chemistry too, in inorganic chemistry, the structure of atom,
atomic mass, number, electronic configuration, etc., are learned.
Study of Periodic Table
Inorganic chemistry in periodic table exclusively deals
with the aspects of the periodic table like arrangement of
elements, the concept of periods and groups, how properties of
elements differ with their position in the periodic table, periodic properties of elements in a
particular period and group etc. Periodic table is the most important tool box for chemists. It
helps us to bring an order into inorganic chemistry. Periodic table is considered as center of
study of inorganic chemistry. It systematizes and rationalizes the chemical facts and helps in
predicting new ones. It suggests fruitful areas for further research.
Study of Individual Group Elements and Block Elements
Each group contains some elements whose properties are similar to each other.
Similarly, each block contains elements which have similar electronic configuration. All these
things are studied under inorganic chemistry, as separate topics. The blocks s, p, d and f are
usually studied separately and then the groups under these blocks, the elements in them, etc
are studied separately.
16

Ores and Alloys
When studying the individual groups, usually, the ores from which the group elements
are extracted, alloys (combination of two or more metals) formed from these elements etc are
studied under inorganic chemistry. 
Chemical Bonding
Since elements exhibit different types of chemical bonding to
form a compound, elements are studied under inorganic chemistry;
the chemical bonding is also a very important topic studied under
inorganic chemistry. Though some part of chemical bonding is also
studied under physical chemistry, main idea about it and the reason
behind an element forming a particular bond is obtained from
inorganic chemistry.
Concept of Acids and Bases
A chemical substance can be acidic or basic. It is very important to study the property
of acids and bases to understand why a particular compound behaves as an acid or a base. The
concept of acids and bases, the theories that explain the behavior of acids and bases etc are
studied under inorganic chemistry.
Coordination Chemistry
This part of inorganic chemistry deals with the study of
complexes. The coordination complexes are very important in day to
day life. So, studying them is necessary to understand them better.
The ligand attached to it, is important, and the geometry of the
complexes are studied under inorganic chemistry.
Nuclear and Radioactivity
The phenomenon of radioactivity is studied both under
physical and inorganic chemistry. Though physical chemistry studies
the theories related to radioactivity, inorganic chemistry deals with
reactions based on radioactivity, nuclear reactions, etc. Radioactivity here helps us understand
the formation of new daughter nuclei from parent nuclei, isotopes, etc.
Types of Chemical Reactions
There are many types of chemical reactions such as decomposition, combustion, acid-
base reaction, etc. All these are studied under inorganic chemistry. It also deals with a very
important type of reaction, called redox reaction, or reduction and oxidation reaction.
Balancing a chemical reaction and a redox reaction is a topic in itself. Balancing of a redox
reaction is more difficult and complicated than balancing a normal chemical reaction. These
are studied thoroughly under inorganic chemistry.
