  2. Polyatomic ion - Wikipedia

    en.wikipedia.org/wiki/Polyatomic_ion

    The term molecule may or may not be used to refer to a polyatomic ion, depending on the definition used. The prefix poly-carries the meaning "many" in Greek, but even ions of two atoms are commonly described as polyatomic. [2] In older literature, a polyatomic ion may instead be referred to as a radical (or less commonly, as a radical group).

  3. Ion - Wikipedia

    en.wikipedia.org/wiki/Ion

    Electrons, due to their smaller mass and thus larger space-filling properties as matter waves, determine the size of atoms and molecules that possess any electrons at all. Thus, anions (negatively charged ions) are larger than the parent molecule or atom, as the excess electron(s) repel each other and add to the physical size of the ion ...

    Nick Brit the Camel ate an Inky Clam with Crêpes for Supper in Phoenix. Number of consonants denotes number of oxygen atoms. Number of vowels denotes negative charge quantity. Inclusion of the word "ate" signifies that each ends with the letters a-t-e. To use this for the -ite ions, simply subtract one oxygen but keep the charge the same.

  5. IUPAC nomenclature of inorganic chemistry 2005 - Wikipedia

    en.wikipedia.org/wiki/IUPAC_nomenclature_of...

    Polyatomic anions made up of different elements are named either substitutively or additively, the name endings are -ide and -ate respectively e.g. : GeH 3 − germanide (substitutive), or trihydridogermanate(1−) (additive) TeH 3 − tellanuide substitutive where -uide specifies anion composed of additional hydride attached to parent hydride

  6. Salt (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Salt_(chemistry)

    Many other inorganic compounds were also found to have similar structural features. [4] These compounds were soon described as being constituted of ions rather than neutral atoms , but proof of this hypothesis was not found until the mid-1920s, when X-ray reflection experiments (which detect the density of electrons), were performed.

  7. Ate complex - Wikipedia

    en.wikipedia.org/wiki/Ate_complex

    The phrase -ate ion or ate ion can refer generically to many negatively charged anions. -ate compound or ate compound can refer to salts of the anions or esters of the functional groups. Chemical terms ending in -ate (and -ite ) generally refer to the negatively charged anions , neutral radicals , and covalently bonded functional groups that ...

  8. Chemistry - Wikipedia

    en.wikipedia.org/wiki/Chemistry

    Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.

  9. Ligand - Wikipedia

    en.wikipedia.org/wiki/Ligand

    Polyatomic ligands such as carbonate are ambidentate and thus are found to often bind to two or three metals simultaneously. Atoms that bridge metals are sometimes indicated with the prefix " μ ". Most inorganic solids are polymers by virtue of the presence of multiple bridging ligands.
