Periodic Videos (also known as The Periodic Table of Videos) is a video project and YouTube channel on chemistry. It consists of a series of videos about chemical elements and the periodic table , with additional videos on other topics in chemistry and related fields.
Periodic table of the chemical elements showing the most or more commonly named sets of elements (in periodic tables), and a traditional dividing line between metals and nonmetals. The f-block actually fits between groups 2 and 3; it is usually shown at the foot of the table to save horizontal space.
Like the periodic table, the list below organizes the elements by the number of protons in their atoms; it can also be organized by other properties, such as atomic weight, density, and electronegativity. For more detailed information about the origins of element names, see List of chemical element name etymologies.
A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
In its logo, which has been a registered trade mark since 2016, the number "42.0" resembles an element on the periodic table. [25] The number was chosen because it is "The Answer to the Ultimate Question of Life, The Universe, and Everything" in Douglas Adams' famous novel The Hitchhiker's Guide to the Galaxy. [26]: 10 m 12 s
English: This pictorial periodic table is colorful, boring, and packed with information. In addition to the element's name, symbol, and atomic number, each element box has a drawing of one of the element's main human uses or natural occurrences. The table is color-coded to show the chemical groupings.
Joseph Priestley and Antoine Lavoisier discover a new gas called oxygen, discrediting the basic theory of chemistry at the time, creating the basis for the modern science of chemistry, and prompting chemists all over the world to look for more new elements; Humphry Davy introduces audiences to nitrous oxide ("laughing gas") and uses electricity to search for new chemical elements.
Poliakoff is the narrator in most of a series of over 600 short videos called The Periodic Table of Videos, [19] [20] a popular science project produced by Brady Haran, originally intended to familiarise the public with all 118 elements of the periodic table.
