Theseare Urdu Medium Notes of Chemistry for class 9. Short questions notes are according to the paper point of view. Urdu Medium Chemistry Notes for class 9 are very helpful for fbise and all other boards of the Punjab Province. These notes are chapters wise which covered all the short questions of 9th class chemistry and MCQs.Read less

I find the notes very easy to read and to understand. All the necessary coverage on each topic made the note a must to have! I only wish there will be more of others such inorganic, analytical, physical, or biochemistry, even the laboratory guideline will make studying a lot easier.

Not only are Chemistry Notes organized and easy-to-digest, but also the author gives many examples and tricks. Personally, I liked two things in these notes: A) The gradual depth of concepts, which saved me the overwhelming feeling one feels when (disorganized) information of so-called "mandatory textbooks" comes exploding from everywhere; B) The abundance of problems and their detailed solutions!

Also, it looks weird, but the professor - on his website - promises to answer FREELY and INSTANTANEOUSLY any email asking a chemistry question through his website. Tell me where you can find such level of service at any University's tutoring center!

I enjoyed using the chemistry notes. It helped me understand what I was teaching to my students. The students liked having all the examples I gave them and I liked how everything was broken down to where the students could understand the information.

Chemistry is the scientific study of the properties and behavior of matter.[1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.[2][3][4][5] Chemistry also addresses the nature of chemical bonds in chemical compounds.

In the scope of its subject, chemistry occupies an intermediate position between physics and biology.[6] It is sometimes called the central science because it provides a foundation for understanding both basic and applied scientific disciplines at a fundamental level.[7] For example, chemistry explains aspects of plant growth (botany), the formation of igneous rocks (geology), how atmospheric ozone is formed and how environmental pollutants are degraded (ecology), the properties of the soil on the Moon (cosmochemistry), how medications work (pharmacology), and how to collect DNA evidence at a crime scene (forensics).

Chemistry has existed under various names since ancient times.[8] It has evolved, and now chemistry encompasses various areas of specialisation, or subdisciplines, that continue to increase in number and interrelate to create further interdisciplinary fields of study. The applications of various fields of chemistry are used frequently for economic purposes in the chemical industry.

The word chemistry comes from a modification during the Renaissance of the word alchemy, which referred to an earlier set of practices that encompassed elements of chemistry, metallurgy, philosophy, astrology, astronomy, mysticism, and medicine. Alchemy is often associated with the quest to turn lead or other base metals into gold, though alchemists were also interested in many of the questions of modern chemistry. [9][10]

The modern word alchemy in turn is derived from the Arabic word al-kīmīā (الكیمیاء). This may have Egyptian origins since al-kīmīā is derived from the Ancient Greek χημία, which is in turn derived from the word Kemet, which is the ancient name of Egypt in the Egyptian language.[11] Alternately, al-kīmīā may derive from χημεία 'cast together'.[12]

The current model of atomic structure is the quantum mechanical model.[13] Traditional chemistry starts with the study of elementary particles, atoms, molecules,[14] substances, metals, crystals and other aggregates of matter. Matter can be studied in solid, liquid, gas and plasma states, in isolation or in combination. The interactions, reactions and transformations that are studied in chemistry are usually the result of interactions between atoms, leading to rearrangements of the chemical bonds which hold atoms together. Such behaviors are studied in a chemistry laboratory.

The chemistry laboratory stereotypically uses various forms of laboratory glassware. However glassware is not central to chemistry, and a great deal of experimental (as well as applied/industrial) chemistry is done without it.

A chemical reaction is a transformation of some substances into one or more different substances.[15] The basis of such a chemical transformation is the rearrangement of electrons in the chemical bonds between atoms. It can be symbolically depicted through a chemical equation, which usually involves atoms as subjects. The number of atoms on the left and the right in the equation for a chemical transformation is equal. (When the number of atoms on either side is unequal, the transformation is referred to as a nuclear reaction or radioactive decay.) The type of chemical reactions a substance may undergo and the energy changes that may accompany it are constrained by certain basic rules, known as chemical laws.

Energy and entropy considerations are invariably important in almost all chemical studies. Chemical substances are classified in terms of their structure, phase, as well as their chemical compositions. They can be analyzed using the tools of chemical analysis, e.g. spectroscopy and chromatography. Scientists engaged in chemical research are known as chemists.[16] Most chemists specialize in one or more sub-disciplines. Several concepts are essential for the study of chemistry; some of them are:[17]

The atom is the basic unit of chemistry. It consists of a dense core called the atomic nucleus surrounded by a space occupied by an electron cloud. The nucleus is made up of positively charged protons and uncharged neutrons (together called nucleons), while the electron cloud consists of negatively charged electrons which orbit the nucleus. In a neutral atom, the negatively charged electrons balance out the positive charge of the protons. The nucleus is dense; the mass of a nucleon is approximately 1,836 times that of an electron, yet the radius of an atom is about 10,000 times that of its nucleus.[19][20]
