The four most common elements in living organisms – carbon, hydrogen, oxygen, and nitrogen – may be remembered with the acronym CHON. To remember the elements necessary for agriculture; C arbon, H ydrogen, Ca lcium, Iron ( Fe ), Magnesium ( Mg ), Manganese ( Mn ), Copper ( Cu ), Mo lybdenum, Chlorine ( Cl ), B oron
To remember the different charges of the anode and cathode in electrolysis (PANIC): Positive Anode Negative Is Cathode. AN OIL RIG CAT: [13] At the ANode, Oxidation Involves electron Loss. Reduction Involves electron Gain at the CAThode. CHON: to remember the four most common elements in organisms; Carbon, Hydrogen, Oxygen, Nitrogen
At standard pressure, carbon, the lightest carbon group element, sublimes at 3825 °C. Silicon's boiling point is 3265 °C, germanium's is 2833 °C, tin's is 2602 °C, and lead's is 1749 °C. Flerovium is predicted to boil at −60 °C. [11] [12] The melting points of the carbon group elements have roughly the same trend as their boiling points ...
The hierarchy of scientific classification. Taxonomy mnemonics are used to memorize the scientific classification applied in taxonomy. They are usually constructed with a series of words that begin with the letters KPCOFGS, corresponding to the initials of the primary taxonomic ranks.
This is a list of mnemonics used in medicine and medical science, categorized and alphabetized. A mnemonic is any technique that assists the human memory with information retention or retrieval by making abstract or impersonal information more accessible and meaningful, and therefore easier to remember; many of them are acronyms or initialisms which reduce a lengthy set of terms to a single ...
This is a list of human anatomy mnemonics, categorized and alphabetized.For mnemonics in other medical specialties, see this list of medical mnemonics.Mnemonics serve as a systematic method for remembrance of functionally or systemically related items within regions of larger fields of study, such as those found in the study of specific areas of human anatomy, such as the bones in the hand ...
In the periodic table of the elements, each column is a group. In chemistry, a group (also known as a family) [1] is a column of elements in the periodic table of the chemical elements. There are 18 numbered groups in the periodic table; the 14 f-block columns, between groups 2 and 3, are not numbered.
Such collisions were especially common early in Earth's history, and these impactors may have been crucial in the formation of the planet's oceans. [ 6 ] The simplest compounds to contain all of the CHON elements are isomers fulminic acid (HCNO), isofulminic acid (HONC), cyanic acid (HOCN) and isocyanic acid (HNCO), having one of each atom.
