WebDec 5, 2024 · Radioactive decay can produce different isotopes of the same element or a lighter element. When the term "chemical element" is used, it can refer to a single atom of that atom or to any pure substance consisting only of that type of iron. For example, an iron atom and a bar of iron are both elements of the chemical element. WebAug 15, 2024 · The f block elements are the lanthanides and actinides and are called the inner transition elements because of their placement in the periodic table due to their electron configurations.

WebJun 7, 2024 · The oxidation state of an element is related to the number of electrons that an atom loses, gains, or appears to use when joining with another atom in compounds. It also determines the ability of an atom to oxidize (to lose electrons) or to reduce (to gain electrons) other atoms or species. Almost all of the transition metals have multiple ... Webf block elements are found outside at the bottom of the periodic table. The name f- blocks because the last electron enters into the f-orbital of the anti-penultimate shell. These are …
