Ions (2024)

FAQs

Ions? ›

An ion is an atom or group of atoms that has an electric charge. Ions with a positive charge are called cations. Ions with a negative charge are called anions. Many normal substances exist in the body as ions. Common examples include sodium, potassium, calcium, chloride, and bicarbonate.

An ion can be defined as a chemical species which holds a positive or negative charge of some magnitude. The term 'ion' can be used to refer to atoms or molecules that have non-zero net charges associated with them.

Common examples include sodium, potassium, calcium, chloride, and bicarbonate. These substances are known as electrolytes. Ions can be created using radiation such as x-rays.

The fours most abundant ions in the body are potassium, sodium, calcium, and chloride.

Ions are formed when an atom gains or loses electrons from the outermost energy shell. Elements form cations when an electron or electrons are lost to achieve a full duplet or octet. If the element gains an electron or more than one electron, it is called an anion.

An ion is a particle like an atom that has lost or gained electrons. Because electrons are negative and protons are positive, differing amounts create a charge. Oppositely charged ions attract just like a magnet and form bonds.

An atom with an electric charge is called an ion. A positively charged ion (a cation) has more protons than electrons. A negatively charged ion (an anion) has more electrons than protons.

Cations play important roles in our daily lives. Sodium, potassium, and magnesium ions are essential for such processes as blood pressure regulation and muscle contraction. Calcium ions are an important part of bone structure. Sodium ions can be used in water softeners to remove other harmful elements.

Ions are everywhere, from our daily surroundings to the cosmic expanse. As common table salt (NaCl) dissolves into sodium (Na⁺) and chloride (Cl^-) ions in water, it imparts a salty taste. Once absorbed by the body, these ions regulate nerve impulses and muscle movements.

ION sees occasional use among the many abbreviations of internet slang, from LOL to STFU. Typically standing for “in other news,” ION signals a change of topic, often abrupt in nature and with a degree of self-deprecation.

What do ions do in the body? ›

Functions of the main electrolytes (ions)

Transmit nerve signals, and contract muscles including the heart, etc. Contract muscles, form bones and teeth, activate enzymes, etc. Regulate osmotic pressure and the body's water content, enable the secretion of stomach acid, etc.

The common ion effect is an effect that suppresses the ionization of an electrolyte when another electrolyte (which contains an ion which is also present in the first electrolyte, i.e. a common ion) is added. It is considered to be a consequence of Le Chatlier's principle (or the Equilibrium Law).

“An ion is a small electrically charged particle. Ions are single charged atoms (simple ions) or small charged “molecules” (polyatomic ions).” Simple ions include Na⁺, Ca²⁺, and Cl^–. Polyatomic ions include (NH₄)⁺, (CO₃)^2-, and OH^–.

a suffix, appearing in words of Latin origin, denoting action or condition, used in Latin and in English to form nouns from stems of Latin adjectives ( communion; union ), verbs ( legion; opinion ), and especially past participles ( allusion; creation; fusion; notion; torsion ).

Ions. Ions are charged atoms, meaning a neutral atom has lost or gained electrons giving the atom an electric charge.

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.
