Chemistry
Chemistry is the scientific discipline involved with compounds composed of atoms, i.e. elements, and molecules, i.e. combinations of atoms: their composition, structure, properties, behavior and the changes they undergo during a reaction with other compounds. 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.
Science
Science (from Latin scientia, meaning "knowledge") is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.
Chemistry
It is a mistake to confound Alchemy with Chemistry. Modern Chemistry is a science which deals merely with the external forms in which the element of matter is manifesting itself. It never produces anything new. We may mix and compound and decompose two or more chemical bodies an unlimited number of times, and cause them to appear under various different forms, but at the end we will have no augmentation of substance, nor anything more than the combinations of the substances that have been employed at the beginning. Alchemy does not mix or compound anything, it causes that which already exists in a latent state to become active and grow. Alchemy is, therefore, more comparable to botany or agriculture than to Chemistry; and, in fact, the growth of a plant, a tree, or an animal is an alchemical process going on in the alchemical laboratory of nature, and performed by the great Alchemist, the power of God acting in nature.
Franz Hartmann. (1890) In the Pronaos of the Temple of Wisdom, containing the History of the True and the False Rosicrucians. p. 129
Chemistry
Chemists usually write about their chemical careers in terms of the different areas and the discrete projects in those areas on which they have worked. Essentially all my chemical investigations, however, are in only one area, and I tend to view my research not with respect to projects, but with respect to where I’ve been driven by two passions which I acquired in graduate school: I am passionate about the Periodic Table (and selenium, titanium and osmium are absolutely thrilling), and I am passionate about catalysis. What the ocean was to the child, the Periodic Table is to the chemist; new catalytic reactivity is, of course, my personal coelacanth.

Alas! A scientific man ought to have no wishes, no affections — a mere heart of stone.
