You know water can be a solid, a liquid, or a gas. So can all kinds of other forms of matter. But how do they change states? Matter does not have to stay the same. It has a lot of ways to change its properties.

Chemistry is the scientific discipline involved with elements and compounds composed of atoms , molecules and ions : their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances. In the scope of its subject, chemistry occupies an intermediate position between physics and biology. Chemistry addresses topics such as how atoms and molecules interact via chemical bonds to form new chemical compounds. There are four types of chemical bonds: covalent bonds, in which compounds share one or more electron s ; ionic bonds , in which a compound donates one or more electrons to another compound to produce ions cations and anions ; hydrogen bonds ; and Van der Waals force bonds. The word chemistry comes from alchemy , which referred to 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, [5] 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.

Textbooks are written form this point of view, and this may be what establishes the supreme importance of numerical problems in student minds And now, equipped with the predictive power of quantum physics, theoretical physicists are beginning to push even further, into new universes and new physics, into controversies once thought to be squarely within the domain of theology or philosophy. As a department of UCL, members of staff are actively involved in teaching both undergraduates and post-graduates. Our post-graduate education programme consists of taught courses, leading to an M epub.
