The meaning of CONCENTRATION is the act or process of concentrating : the state of being concentrated; especially : direction of attention to a single object. How to use concentration in a sentence.
Concentration was an NBC in-house production, apart from the earliest episodes. As a result of the 1950s quiz scandals, the network purchased the rights to Concentration and three other games (Twenty-One, Dough Re Mi and Tic-Tac-Dough) from producers Barry and Enright.

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 opposite to the charge of a …
Ion, any atom or group of atoms that bears one or more positive or negative electrical charges. Positively charged ions are called cations; negatively charged ions, anions.
The Ion District is a 16-acre innovation hub in Houston’s Midtown, developed by Rice University to foster collaboration among entrepreneurs, academics, startups, and established companies.
Ions are atoms that have a positive or negative charge because they have unequal numbers of protons and electrons. If atoms lose electrons, they become positive ions, or cations. If atoms gain …
This page explains ions as charged particles from atom electron gain or loss. Cations are positive ions from lost electrons, while anions are negative ions from gained electrons. Naming conventions …
The meaning of ION is an atom or group of atoms that carries a positive or negative electric charge as a result of having lost or gained one or more electrons. How to use ion in a sentence.
A new prototype ion engine known as a lithium-fed magnetoplasmadynamic (MPD) thruster has passed a crucial test at NASA. The space agency is hoping to eventually combine this technology …
A prototype ion engine that uses lithium metal vapor as a propellant has aced its first tests, achieving 25 times more power than the ion engine on the Psyche mission.
In chemistry, the definition of an ion is an electrically charged atom or molecule. This means the atom or molecule has an unequal number of protons and electrons.

If an atom loses or gains electrons, it will become a positively or negatively charged particle, called an ion. The loss of one or more electrons results in more protons than electrons and an overall positively …
Learn the definition of an ion, as used in chemistry, chemical engineering, and physics, plus review examples of ions.
Read this tutorial to learn about what an ion is, the differently charged ions, and how they are involved in different branches of chemistry!
Ionic bonds form when the valence (outermost) electrons of one atom are transferred permanently to another atom following the octet rule. The atom that loses electrons becomes a positively charged ion, …
