It is often seen as linked to the quest to turn lead or another common starting material into gold,  though in ancient times the study encompassed many of the questions of modern chemistry being defined as the study of the composition of waters, movement, growth, embodying, disembodying, drawing the spirits from bodies and bonding the spirits within bodies by the early 4th century Greek-Egyptian alchemist Zosimos.
The current model of atomic structure is the quantum mechanical model. This matter can be studied in solid, liquid, or gas statesin isolation or in combination.
The interactionsreactions 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. Solutions of substances in reagent bottles, including ammonium hydroxide and nitric acidilluminated in different colors A chemical reaction is a transformation of some substances into one or more different substances.
It can be symbolically depicted through a chemical equationwhich 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 structurephase, as well as their chemical compositions. They can be analyzed using the tools of chemical analysise. Scientists engaged in chemical research are known as chemists.
Several concepts are essential for the study of chemistry; some of them are: Matter In chemistry, matter is defined as anything that has rest mass and volume it takes up space and is made up of particles. The particles that make up matter have rest mass as well — not all particles have rest mass, such as the photon.
Matter can be a pure chemical substance or a mixture of substances. Atom A diagram of an atom based on the Bohr model 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 nucleonswhile the electron cloud consists of negatively charged electrons which orbit the nucleus.THE KRIZNER GROUP is a full service law firm that concentrates its practice in assisting organizations both before and after disputes arise.
