Electronic structures of Cations. A cation (positively charged ion) forms when one or more electrons are removed from a parent atom. When forming a cation, an atom of a main group element tends to lose all of its valence electrons, thus becoming isoelectronic with the previous noble gas in the periodic …
WebGood reducing agents include the active metals, such as sodium, magnesium, aluminum, and zinc, which have relatively small ionization energies and low electro-negativities. Metal hydrides, such as NaH, CaH 2, and LiAlH 4, which formally contain the H - ion, are also good reducing agents.
