Like English, French sometimes uses (or historically used) a particle Ô to mark vocative phrases rather than by change to the form of the noun. A famous example is the title and first line of the Canadian national anthem, O Canada (French title: Ô Canada ), a vocative phrase addressing Canada .
In modern grammar, a particle is a function word that must be associated with another word or phrase to impart meaning, i.e., it does not have its own lexical definition. [citation needed] According to this definition, particles are a separate part of speech and are distinct from other classes of function words, such as articles, prepositions, conjunctions and adverbs.
In linguistics, a vocative or vocative expression is a phrase used to identify the addressee of an utterance. The underlined phrases in each of the following English sentences are examples of vocatives: Sir, your table is ready. I'm afraid, Mr. Renault, that your card has been declined. Quit playing around, bozo.
In particle physics, every type of particle has an associated antiparticle with the same mass but with opposite physical charges such as electric charge. For example, the antiparticle of the electron is the antielectron (which is often referred to as the positron).
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
Scientific terminology is the part of the language that is used by scientists in the context of their professional activities. While studying nature, scientists often encounter or create new material or immaterial objects and concepts and are compelled to name them.

Since then, the particle has been shown to behave, interact, and decay in many of the ways predicted for Higgs particles by the Standard Model, as well as having even parity and zero spin, two fundamental attributes of a Higgs boson. This also means it is the first elementary scalar particle discovered in nature.
