"He" is the chemical symbol for Helium, an element on the periodic table with atomic number 2. Helium is a colorless, odorless, and inert noble gas, meaning it doesn't easily react with other elements. It is the second most abundant element in the universe, commonly found in stars, incl...
Only elements go onto the periodic table, andsteel is an alloy, not an element.Steelis made from multiple elements. Its basic formula includesiron(Fe) with trace amounts of carbon (C). Different types of steel made add other elements to enhance properties. For example, chromium (Cr) may ...
All of these events (possibly with the exception of X-ray bursts) eject material with an abundance composition unique to the specific event and lead over time to the evolution of elemental (and isotopic) abundances in the galactic gas and their imprint on the next generation of stars. In ...
The superheavy elements, or those with atomic numbers above 104, also fit into this non-natural category. The larger the atom's nucleus — which increases with the number of protons inside — the more unstable that element is, generally. As such, these outsized elements are fleeting, lasting...
(osmosis control), in the case of the phloem. Inside the vascular tissues, the REE can bind reversibly to anions such as COOH−, with the degree of bonding varying according to the atomic number of the element of interest [97], which may also influence the accumulation of these elements...
