an atom that has lost or gained one or more electrons. Thus, a positively charged ion is one that has lost an electron and a negatively charged ion is one that has gained an electron.
chemicals (i.e., atoms or molecules) with positive charges ( cations) or negative charges ( anions). common ions found in fresh water include: sodium (Na+), chloride (Cl-), sulfate (SO-), carbonates (HCO-, CO-) and nitrate (NO-).
Atoms, groups of atoms, or compounds that are electrically charged as a result of the loss of electrons ( cations) or the gain of electrons ( anions).
an atom that carries a positive or negative electrical charge as a result of having lost or gained one or more electrons
Positively or negatively charged particles.
Atoms or molecules that have gained or lost electrons, thus acquiring a positive or negative charge.
an atom with one or more electrons stripped off, giving it a net positive charge.
An atom or a group of atoms with an electric charge.
the electrically charged state that an element assumes in true solution. In the ionic state, ions are chemically reactive. Some ions, such as, copper, silver and zinc, are used as sanitizers in mineral purifiers and/or ionizers.
Atoms or groups of atoms that have an electrical charge.
Electrically charged particles formed when an atom or molecule gains or loses electrons. Electricity and magnetism
Molecules that have had electrons stripped off them or added to them, so have a charge. Ions are usually either air ions or ions in solution such as in cells.
Atoms or small molecules that carry an electric charge. The movement of ions across cell membranes leads to electrical signalling in the brain.
Electrically charged atoms that have gained or lost electrons.
Atoms which have the same number of electrons and protons have zero charge since the number of positively charged protons equals the number of negatively charged electrons. If an atom has more electrons than protons, it has a negative charge and is called a negative ion. Atoms that have fewer electrons than protons are positively charged and are called positive ions. Some forms of radiation can strip electrons from atoms.
Molecules or atoms which carry a positive (cations) or negative (anions) electrical charge.
Atom with an unbalanced electrical charge caused by the loss or gain of one or more electrons.
Atoms with positive or negative charges. Often part of a salt (like Na+ or Cl- from NaCl.)
Any atom or group of atoms that has a positive or negative charge. This charge is created by the removal or addition of one or more electrons.
Atoms or molecules in which the number of electrons do not equal the number of protons, giving it either a positive or negative charge. Positively-charged ions are called "cations," while negatively-charged ions are called "anions."
Electrically charged molecules, or molecule fragments.
Ions are atoms with unequal numbers of electrons and protons, and which, therefore, have an electric charge. If an atom has more electrons than protons, it has a negative charge, and is called a negative ion. Atoms which have fewer electrons than protons are positively charged, and are called positive ions.
Electrically charged atoms resulting from the loss of electrons (cations) or gain of electrons (anions).
An electrically charged particle, formed when an atom loses or gains one or more electrons to form a stable outer shell. All ions are either cations or anions.
An atom or a group of atoms that has acquired a net electric charge by gaining or losing one or more electrons. Reference: B1
Atoms or groups of atoms that are electrically charged as a result of the loss (cation) or gain of electrons (anion).
atoms or molecules that have lost or gained one or more electrons, thus having a positive or negative charge;
Electrically charged atoms or groups of atoms that are capable of conducting an electrical current in water. They may be positively or negatively charged. In neutral water, there are equal concentrations of hydrogen (H+) ions and hydroxyl (OH-) ions. Salt water has significant amounts of sodium (Na+) and chloride (Cl-) ions.
An atom or molecule or group of atoms that have an electric charge, either positive or negative.
An electrically charged atom or group of atoms. Such loss or gain of electrons occurs during chemical reactions in which electrons are transferred from one atom to another; by the action of matter on x-rays, UV light and certain other forms of radiant energy or by the impact of alpha and beta particles, protons or deuterons, etc. on atoms and molecules.
These are atoms with an electrical charge; positively charged ions are called cations and negatively charged ions are known as anions. One theory concerning the processes of magnetic therapy is that it ionizes the blood.
Atoms or molecules that have a net electrical charge. In semiconductor manufacturing, ions are the source of chemical impurities that alter the conductivity of silicon.
Atoms that carry an electric charge, either positive or negative. If an atom gains an electron it takes on a negative charge. If the atom loses an electron it takes on a positive charge.
An atom or group of atoms which is electrically charged. Depending on how they were created - through release or absorption - ions can be either positively or negatively charged.
Charged particles formed by loss or gain of electrons. When atoms lose an electron they become a positive ion. When they gain an electron they become a negative ion. Classifying materials
