Chemistry is a branch of physical science that studies the composition, structure, properties and change of matter. Chemistry includes topics such as the properties of individual atoms, how atoms form chemical bonds to create chemical compounds, the interactions of substances through intermolecular forces that give matter its general properties, and the interactions between substances through chemical reactions to form different substances.
Chemistry is sometimes called the central science because it bridges other natural sciences, including physics, geology and biology. For the differences between chemistry and physics see Comparison of chemistry and physics.
Scholars disagree about the etymology of the word chemistry. The history of chemistry can be traced to alchemy, which had been practiced for several millennia in various parts of the world.
The word chemistry comes from the word alchemy which was an earlier set of practices that encompassed elements of chemistry, metallurgy, philosophy, astrology, astronomy, mysticism and medicine. It is often seen as linked to the quest to turn lead or another common starting material into gold. Alchemy, which was practiced around 330, is the study of the composition of waters, movement, growth, embodying, disembodying, drawing the spirits from bodies and bonding the spirits within bodies (Zosimos). An alchemist was called a 'chemist' in popular speech, and later the suffix "-ry" was added to this to describe the art of the chemist as "chemistry".
A ballroom is a large room inside a building, the designated purpose of which is holding large formal parties called balls. Traditionally, most balls were held in private residences; many mansions contain one or more ballrooms. In other large houses, a large room such as the main drawing room, long gallery, or hall may double as a ballroom, but a good ballroom should have the right type of flooring, such as hardwood flooring or stone flooring (usually marble).
Ballrooms are generally quite large, and may have ceilings higher than other rooms in the same building. The large amount of space for dancing, as well as the highly formal tone of events have given rise to ballroom dancing. The largest balls are now nearly always held in public buildings, and many hotels have a ballroom. They are also designed large to help the sound of orchestras carry well throughout the whole room.
A special case is the annual Vienna Opera Ball, where, just for one night, the auditorium of the Vienna State Opera is turned into a large ballroom. On the eve of the event, the rows of seats are removed from the stalls, and a new floor, level with the stage, is built.

Hank does his best to convince us that chemistry is not torture, but is instead the amazing and beautiful science of stuff. Chemistry can tell us how three tiny particles - the proton, neutron and electron - come together in trillions of combinations to form ... everything. In this inaugural episode of Crash Course Chemistry, we start out with one of the biggest ideas in chemistry ever - stuff is made from atoms. More specifically, we learn about the properties of the nucleus and why they are important to defining what an atom actually is.

Hi Everyone!!! So in this video I talk to you guys about what I did in order to get an A in all my chemistry classes as well as some important chemistry topics. Don't get me wrong I worked very hard to get these grades, sadly I'm not naturally gifted with being a genius in chemistry, and so I know that if you guys work hard as well you will do amazing! Thank you guys so much for watching and make sure to let me know what you think about this video. Study hard everyone and I wish you all the best of luck :) Gabby ________________________ C O N N E C T Instagram: http://instagram.com/makeupwarrior1 Email gabriella.aikawa@gmail.com ________________________ V I D E O S M E N T I O N E D : How to get an A in Organic Chemistry: https://www.youtube.com/watch?v=YQkcNeIgdoU Study Guide...
