    en.wikipedia.org/wiki/Monatomic_ion

    Ion. (Redirected from Monatomic ion) Electron transfer between lithium (Li) and fluorine (F). Forming an ionic bond, Li and F become Li + and F − ions. An ion (/ ˈaɪ.ɒn, - ən /) [1] is an atom or molecule with a net electrical charge. The charge of an electron is considered to be negative by convention and this charge is equal and ...

  3. Atomicity (chemistry) - Wikipedia

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

    Atomicity (chemistry) Atomicity is the total number of atoms present in a molecule of an element. For example, each molecule of oxygen (O 2) is composed of two oxygen atoms. Therefore, the atomicity of oxygen is 2. [1] In older contexts, atomicity is sometimes equivalent to valency. Some authors also use the term to refer to the maximum number ...

    en.wikipedia.org/wiki/List_of_chemistry_mnemonics

    Cations are positively (+) charged ions while anions are negatively (−) charged. This can be remembered with the help of the following mnemonics. Cats have paws ⇔ Cations are pawsitive. [23] Ca+ion: The letter t in cation looks like a + (plus) sign. [24] An anion is a negative ion. (An egative ion ⇒ Anion). [25]

  5. Monatomic gas - Wikipedia

    en.wikipedia.org/wiki/Monatomic_gas

    Monatomic gas. In physics and chemistry, "monatomic" is a combination of the words "mono" and "atomic", and means "single atom ". It is usually applied to gases: a monatomic gas is a gas in which atoms are not bound to each other. Examples at standard conditions of temperature and pressure include all the noble gases (helium, neon, argon ...

  7. Charge number - Wikipedia

    en.wikipedia.org/wiki/Charge_number

    Charge number (denoted z) is a quantized and dimensionless quantity derived from electric charge, with the quantum of electric charge being the elementary charge (e, constant). The charge number equals the electric charge (q, in coulombs) divided by the elementary charge: z = q / e. Atomic numbers (Z) are a special case of charge numbers ...

  9. Chemical species - Wikipedia

    en.wikipedia.org/wiki/Chemical_species

    Generally, a chemical species is defined as a chemical identity that has the same set of molecular energy levels in a defined timescale (i.e. an experiment). These energy levels determine the way the chemical species will interact with others through properties such as bonding or isotopic compositions. The chemical species can be an atom ...
