A Basic Introduction to Chemistry: Definition, Branches, Physical properties of the four states of matter

 How to define Chemistry?

The knowledge that humans have developed through observations and experimentation may be stated to as science. Due to its immense development and variety of subjects, science has been further divided into many branches. One of the most significant fields of science is chemistry. Chemistry is the study of the composition, structure, and properties of matter and the processes that matter undergoes. Since living and non-living things are made up of matter chemistry influences all aspects of life. There are Several branches of chemistry as mentioned below.

Branches of chemistry

1. Organic chemistry— Study of carbon-containing compounds. (Petroleum, Plastics, biofuels, etc)

2. Inorganic chemistry— Study of organic substances bonded to metals (organometallics, metal alloys, ion batteries, glass, etc)

3. Physical chemistry— Study of the properties and changes of matter and their relation to energy (plasma TVs -  television display technology, energy production, etc)

4. Analytical chemistry— Identification of the components and composition of materials (blood analysis, water analysis, pollution testing, etc)

5. Biochemistry— Study of substances and processes occurring in living things (Medical, pharmaceuticals, etc)

6. Theoretical chemistry— Use of mathematics and computers to understand the principles of chemical behavior and to design and predict the properties of new compounds (docking, DFT studies)

State of matter

There are four fundamental states of matter namely solid, liquid, gas and plasma. The state of a substance may be changed by adding or removing heat energy from it. For instance, the addition of heat can melt ice into liquid water and turn that water into steam.

Group 1 on the periodic table: Alkali metals - Electronic configuration, physical and chemical properties

Image
  What are Alkali Metals? Alkali metals are s-block elements located in the leftmost side of the periodic table.   The word ‘alkali’ refers to the basic or alkaline nature of their metal hydroxides. Alkali metals are a group of six chemical elements in the first column of the periodi c table namely Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Cesium (Cs), and Francium (Fr).  Electronic configuration Alkali metals have a corresponding [Noble gas] ns1 electronic configuration. So, all alkali metals have one electron in their outermost layer of electrons.    Physical and chemical Properties: Like all metals alkali metals are shiny in appearance and good conductors of electricity; however, they are soft and highly reactive. They have low melting points and react easily with air and moisture. Because of their reactivity, special precautions are needed when using and storing them.  Francium is a radioactive element ...

NCERT grade 10 Science Chapter 1: Types of Chemical Reactions– Concepts and explanation: Part 4 Corrosion

Image
  What is Corrosion? Corrosion is a common phenomenon that transforms a refined material into a more chemically stable form, such as its oxide, hydroxide, or sulfide.   You must have noticed that some iron objects are covered with an orange or reddish-brown coloured layer at some point in time when exposed to moisture in air for a long time. The formation of this layer is the result of a chemical process known as rusting, which is a form of corrosion. Corrosion Definition It is basically defined as a natural process that causes the transformation of pure metals into undesirable substances when they react with substances like water or air. This reaction causes damage of metal as it interfaces with the environment and gradually spreads to the entire bulk of the metal. The following image show a corroded iron pipe.   Do All Metals Corrode? Metals placed higher in the reactivity series, such as iron, zinc, etc., get corroded very easily, and metals placed lower in...

Introduction to Structure of Atom and properties - Electrons, Protons, Neutrons and Models of Atom

Image
  What is an atom? An atom is the basic building block of matter that cannot be chemically broken.  Atoms organize all kinds of matter; everything you can see and touch. The atom is the  smallest particle into which an element can be divided .  Subatomic particles Atoms consist of three basic particles namely, neutrons, protons and electrons with hydrogen as an exception without neutrons. The nucleus of the atom contains protons and neutrons. It is nuclear energy that makes neutrons and protons stick together. And, nucleus bounds with one or more electrons around it. The protons are positively charged, electrons are negatively charged and neutrons are neutral. Protons, neutrons, and electrons are very small, and most of the volume of an atom is actually empty space.  The number of protons in an atom's nucleus distinguishes one chemical element from another.  When a  chemical reaction  occurs, it is preserved with its original proper...
