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.
This is a list of chemical elements and their atomic properties, ordered by atomic number (Z).. Since valence electrons are not clearly defined for the d-block and f-block elements, there not being a clear point at which further ionisation becomes unprofitable, a purely formal definition as number of electrons in the outermost shell has been used.
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.
AsapScience, stylized as AsapSCIENCE, is a YouTube channel created by Canadian YouTubers Mitchell Moffit and Gregory Brown. The channel produces a range of videos that touch on various concepts related to science and technology. [1] AsapScience is one of the largest educational channels on YouTube.

The following outline acts as an overview of and topical guide to chemistry: . Chemistry is the science of atomic matter (matter that is composed of chemical elements), especially its chemical reactions, but also including its properties, structure, composition, behavior, and changes as they relate to the chemical reactions.
Sir Martyn Poliakoff (born 16 December 1947) [3] is a British chemist known for his work on green chemistry and for being the main presenter on the popular YouTube channel Periodic Videos. [6] The core subjects of his academic work are supercritical fluids, [7] [8] infrared spectroscopy and lasers.
A period on the periodic table is a row of chemical elements. All elements in a row have the same number of electron shells. Each next element in a period has one more proton and is less metallic than its predecessor. Arranged this way, elements in the same group (column) have similar chemical and physical properties, reflecting the periodic law.
