An ion is an atom or molecule in which the total number of electrons is not equal to the total number of protons, giving it a net positive or negative electrical charge. The name was given by physicist Michael Faraday for the substances that allow a current to pass ("go") between electrodes in a solution, when an electric field is applied. It is from Greek ιον, meaning "going." The word ion also is responsible for electrical current being symbolized by the letter i in chemistry and physics.
An anion (pronounced /ˈæn.aɪ.ən/ AN-eye-ən), from the Greek word ἄνω (ánō), meaning "up", is an ion with more electrons than protons, giving it a net negative charge (since electrons are negatively charged and protons are positively charged).

One particular cation (that of hydrogen) contains no electrons, and thus is very much smaller than the parent hydrogen atom.
Natural Occurrences
Ions are ubiquitous in nature and are responsible for diverse phenomena from the luminescence of the Sun, and the existence of ionosphere on Earth. Atoms in their ionic state may have a different color from neutral atoms, and thus light absorption by metal ions gives the color of gemstones. In both inorganic and organic chemistry (including biochemistry), the interaction of water and ions is extremely important (an example is the energy that drives breakdown of ATP. The following sections describe contexts in which ions feature prominently and are arranged in decreasing physical length-scale, from the astronomical to the microscopic.
Astronomical
The remnant of "Tycho's Supernova", a huge ball of expanding plasma. The outer shell shown in blue is X-ray emission by high-speed electrons.
Main article: Plasma (physics)
A collection of non-aqueous gas-like ions, or even a gas containing a proportion of charged particles, is called a plasma. >99.9% of visible matter in the Universe may be in the form of plasmas.[3] These include our Sun and other stars, the space between planets, as well as the space in between stars. Plasmas are often called the fourth state of matter because its properties are substantially different from
* Protons and electrons have equal and opposite electrical charges. Protons are positively charged, and electrons are negatively charged.
A sodium ion (Na+) occurs when a sodium atom loses an electron and gains a positive charge
Alpha: is a helium nucleus and is made up of 2 protons and neutron and has a positive charge. When it is ionizing it can knock out the electrons because of the collisions.
One of these properties is called an electrical charge. Protons have a "positive" (+) charge, electrons have a "negative" (-) charge, and neutrons have no charge, they are neutral.
In the nucleus of an atom there are protons and neutrons the number of protons and neutrons depends on the element and ,if it is an isotope of that element. E.g. carbon 12, carbon 12 has six neutrons six protons and 6 electrons . Electrons are located around the nucleus of the atom. Electrons are in shells, the shell closest to the nucleus is 1 , the one after 2 and so on. Each shell can only hold up to a certain number of electrons . the first can hold up to 2 , the second 8 (2+6) the third up to 18 (2+6+10). The general formula for finding out how many electrons a shell can hold is 2n^2. Electrons have a negative charge , while protons have a positive and neutrons have no charge. A atom has the same number of protons and electrons. An ion is formed when an atom loses or gains a electrons .
3. Electrons are small and are negatively charged (-) with a mass of almost 0 amu..
The oxidation number of an atom of any free element is ZERO. Means to say there is only one kind of atom present, no charge.
It can also be defined as a type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound (Britannica). Another thing is positive ions can be called a cation and negative ions can be called an anion
A topic of great importance to all scientists is the identification of compounds, which is relevant in all aspects of their work in some way shape or form. Weather it may be determining what is causing sickness or what is polluting the air, it is very prevalent in the science world. In project 2, identification of cations and anions was preformed through a series of confirmation and elimination tests that ultimately led to identifying an unknown ionic compound made of cations and anions.
In ionic bonding one atom transfers electrons to another, creating ions with differing electrical charge.
Electrolytes are compounds that dissociate into ions when they are dissolved in water, thereby causing them to become electrically charged particles, meaning that they have the ability to conduct electrical impulses. The electrical impulses created are what the body needs in order to make muscle cells contract. Electrolytes can become either cations (positively charged) or anions (negatively charged).
Introduction: The purpose of this lab was to study the specific characteristics of cations and anions,
Introduction: The purpose of this lab was to find the relative solubilities of some salts of the Alkaline Earths and use that information to find the order which they appear in the periodic table; also use that information to efficiently find an unknown alkaline earth halide. Also to find the relative oxidizing powers of the Halogens given and using that information finding the order of the Halogens in the periodic table; also use that information to efficiently find an unknown Halogen.
The chemical reaction which occurs between the electrolyte and the positive electrode internally in the battery then produces a buildup of positive ions, which are atoms that are missing electrons. The positive ions buildup at the cathode of the battery which
An Atom is the the basic building block of all matter. Atoms are made up of Particles, called: Protons, neutrons and Electrons. Protons carry a positive charge, the neutron carry 's a neutral charge and the electron carry’s a negative charge. The Atom has two main parts the Nucleus and the Electron Shell. The Nucleus contains the Protons and Neutrons. The electron Shell Contains the The electrons.
