- Atoms vs. Ions. Atoms are neutral; they contain the same number of protons as electrons. By definition, an ion is an electrically charged particle produced by either removing electrons from a neutral atom to give a positive ion or adding electrons to a neutral atom to give a negative ion. When an ion is formed, the number of protons does not change. Neutral atoms can be turned into positively charged ions by removing one or more electrons. A neutral sodium atom, for example, contains 11 protons and 11 electrons. By removing an electron from this atom we get a positively charged Na + ion that has a net charge of +1. Atoms that gain extra electrons become negatively charged.

Ionic Compound Definition of ionic compoundAn ionic compound is composed of cations and anions joined together. Such compounds are held together by electrostatic forces, and adopt structures that maximize the attraction of oppositely charged species and minimize the repulsion between charged species with the same sign.n ionic compounds the constituent elements exist as ions. Ions are atoms or groups of atoms that carry a charge by virtue of losing or gaining one or more electrons. Ionic compounds result from the combination of a positive ion known as a cation and a negative ion called an anion.

- In chemistry, an ionic compound is a chemical compound in which ions are held together in a structure by electrostatic forces termed ionic bonds.The positively charged ions are called cations and the negatively charged ions are called anions.onic compounds without the acidic hydrogen ion (H +), or the basic ions hydroxide (OH −) or oxide (O 2−), are also known as salts and can be formed by acid-base reactions.

How is an ion formed? Ions are formed when an atom either gains or loses electrons. A normal atom has equal numbers of protons (positively charged) and electrons (negatively charged). When an electron is lost, the resulting ion is now positively charged (called a cation). Most metals are prone to losing electrons.

- From Wikipedia. Salt (chemistry). In chemistry, salts are ionic compounds that can result from the neutralization reaction of an acid and a base. They are composed of cation s (positively charged ions) and anion s (negative ions) so that the product is electrically neutral (without a net charge).any living bodies including human body also contains some kinds of acids and bases. A very common acid is the dilute Hydrochloric acid present in our stomach, which involves in the digestion process of food materials in stomach. Urine, blood, and intestinal fluid are alkaline in nature.

Ion An ion (/ ˈ aɪ ə n, - ɒ n /) is an atom or molecule that has a non-zero net electrical charge (its total number of electrons is not equal to its total number of protons). A cation is a positively-charged ion, while an anion is negatively charged.

Atom Ions. Atoms are normally electrically neutral; they have no charge. However, electrons in the valence shell can be gained or lost (depending on the element and the conditions) to form an ion. An atom that loses electrons becomes positively charged and is known as a cation.

Salt (chemistry) In chemistry, a salt is an ionic compound that can be formed by the neutralization reaction of an acid and a base. Salts are composed of related numbers of cations and anions so that the product is electrically neutral. These component ions can be inorganic, such as chloride, or organic, such as acetate; and can be monatomic, such as fluoride, or polyatomic, such as sulfate. There are several varieties of salts. Salts that hydrolyze to produce hydroxide ions when dissolved in water are alkali sa

Ions: Atoms with an Electrical Charge Atoms (or groups of atoms) in which there are unequal numbers of protons and electrons are called ions. Usually, the number of protons and electrons in atoms are equal. But there are cases in which an atom can acquire an electrical charge.

Ion An ion is an electrically charged atom or group of atoms. It is a part of an atom, or part of a group of atoms (molecule). It is  charged  so it will move near electricity. This is because atoms are made of three smaller parts (1) neutrons (with no charge), and equal numbers of (2) charged protons and (3) oppositely-charged electrons. An ion has unequal numbers of protons and electrons. Making an ion from an atom or molecule is called ionization. The charge on a proton is measured as +1 (positively charged), and the charge on an electron is measured as -1 (negatively charged).

- i·on·ic bond. A chemical bond formed between two ions with opposite charges. Ionic bonds form when one atom gives up one or more electrons to another atom. These bonds can form between a pair of atoms or between molecules and are the type of bond found in salts. See more at bond, coordinate bond, covalent bond.
