Standard atomic weight A r °(V) 50.9415 ... Amanita muscaria and related species of macrofungi accumulate vanadium (up to 500 mg/kg in dry weight).
Several species of macrofungi accumulate vanadium (up to 500 mg/kg in dry weight). [97] Vanadium-dependent bromoperoxidase generates organobromine compounds in a number of species of marine algae. [98] Rats and chickens are also known to require vanadium in very small amounts and deficiencies result in reduced growth and impaired reproduction. [99]

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 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
Naturally occurring vanadium (23 V) is composed of one stable isotope 51 V and one radioactive isotope 50 V with a half-life of 2.71×10 17 years. 24 artificial radioisotopes have been characterized (in the range of mass number between 40 and 65) with the most stable being 49 V with a half-life of 330 days, and 48 V with a half-life of 15.9735 days.
An average 70 kg human body is about 0.01% heavy metals (~7 g, equivalent to the weight of two dried peas, with iron at 4 g, zinc at 2.5 g, and lead at 0.12 g comprising the three main constituents), 2% light metals (~1.4 kg, the weight of a bottle of wine) and nearly 98% nonmetals (mostly water).
It contains a table of main isotopes and eventually the standard atomic weight. This template is reused in {{Infobox <element>}} as a child Infobox (|child=yes). As of Jan 2023, a 'Main isotope' is conforming MOS:MAINISOTOPE (under construction, see WP:ELEMENTS What is a "Main_isotope"?) Each isotope has its own row, with decay modes:
Just as atomic units are given in terms of the atomic mass unit (approximately the proton mass), the physically appropriate unit of length here is the Bohr radius, which is the radius of a hydrogen atom. The Bohr radius is consequently known as the "atomic unit of length". It is often denoted by a 0 and is approximately 53 pm. Hence, the values ...
