List of chemical elements. 118 chemical elements have been identified and named officially by IUPAC. A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z ). [1]
Lessons in Chemistry is a novel by Bonnie Garmus.Published by Doubleday in April 2022, it is Garmus's debut novel. It tells the story of Elizabeth Zott, who becomes a beloved cooking show host in 1960s Southern California after being fired as a chemist four years earlier. [4]
Antoine-Laurent de Lavoisier (/ l ə ˈ v w ɑː z i eɪ / lə-VWAH-zee-ay; [1] [2] [3] French: [ɑ̃twan lɔʁɑ̃ də lavwazje]; 26 August 1743 – 8 May 1794), [4] also Antoine Lavoisier after the French Revolution, was a French nobleman and chemist who was central to the 18th-century chemical revolution and who had a large influence on both the history of chemistry and the history of biology.
Methyl group. In organic chemistry, a methyl group is an alkyl derived from methane, containing one carbon atom bonded to three hydrogen atoms, having chemical formula CH3 (whereas normal methane has the formula CH4 ). In formulas, the group is often abbreviated as Me. This hydrocarbon group occurs in many organic compounds.
Chemistry. The 1871 periodic table constructed by Dmitri Mendeleev. The periodic table is one of the most potent icons in science, lying at the core of chemistry and embodying the most fundamental principles of the field. The history of chemistry represents a time span from ancient history to the present.
The alkyl (R') group is named first. The R−C(=O)O part is then named as a separate word based on the carboxylic acid name, with the ending changed from "-oic acid" to "-oate" or "-carboxylate" For example, CH 3 CH 2 CH 2 CH 2 COOCH 3 is methyl pentanoate, and (CH 3) 2 CHCH 2 CH 2 COOCH 2 CH 3 is ethyl 4-methylpentanoate.
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.
