The word chemistry derives from the word alchemy, which is found in various forms in European languages. The word 'alchemy' itself derives from the Arabic word al-kīmiyāʾ ( الكيمياء ), wherein al- is the definite article 'the'. The ultimate origin of the word is uncertain, [ 1] but the Arabic term kīmiyāʾ ( كيمياء) is likely ...
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.
The protoscience of chemistry, and alchemy, was unsuccessful in explaining the nature of matter and its transformations. However, by performing experiments and recording the results, alchemists set the stage for modern chemistry. The history of chemistry is intertwined with the history of thermodynamics, especially through the work of Willard ...
Named in honour of Glenn T. Seaborg, who discovered the chemistry of the transuranium elements, shared in the discovery and isolation of ten elements, and developed and proposed the actinide series. · Former names: eka-tungsten, [21] unnilhexium (Unh, '106'): temporary systematic name and symbol. [61] [22] Bohrium (Bh) 107 Bohr, Niels: eponym
Science is a strict systematic discipline that builds and organises knowledge in the form of testable hypotheses and predictions about the world. [1] [2] Modern science is typically divided into three major branches: [3] the natural sciences (e.g., physics, chemistry, and biology), which study the physical world; the social sciences (e.g., economics, psychology, and sociology), which study ...
Allium sativum is a perennial flowering plant that grows from a bulb. It has a tall, erect flowering stem that grows up to 1 m (3 ft). The leaf blade is flat, linear, solid, and approximately 1.25–2.5 cm (0.5–1.0 in) wide, with an acute apex. The plant may produce pink to purple flowers from July to September in the Northern Hemisphere.
Silver is a chemical element; it has symbol Ag (from Latin argentum 'silver', derived from Proto-Indo-European *h₂erǵ 'shiny, white') and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. [ 8]
