what are ions simple definition?
173411
an electrically charged atom or group of atoms formed by the loss or gain of one or more electrons, as a cation (positive ion), which is created by electron loss and is attracted to the cathode in electrolysis, or as an anion (negative ion), which is created by an electron gain and is attracted to the anode.

Neutral atoms: Number of electron, number of protons. Ions: protons the same, electrons are different. Either lost or gained electrons. Ions are atoms or groups of atom with a positive or negative charge.

Difference Between Anions and Cations. An anion may be defined as an atom or molecule that is negatively charged. A cation may be defined as an atom or molecule that is positively charged. Anions and cations are both ions.

No, an element is where all atoms have the same number of protons. An ion is an atom that has different number of protons and electrons.
175733
Ions form from elements when they gain or lose an electron causing the number of protons to be unequal to the number of electrons, resulting in a net charge. If there are more electrons than protons (from an element gaining one or more electrons), the ion is negatively charged and called an anion.

An atom that has fewer neutrons than protons and more electrons than protons is an anion. Ion are charged particles. ... Electrons are negatively charged particles, therefore, there excess will be define an ion as anion.

Ions: Atoms with an Electrical Charge. Atoms (or groups of atoms) in which there are unequal numbers of protons and electrons are called ions.

Ion is electrically charged atom. Ground state or excited state atom is still an electrically neutral atom. An ion is any atom or sometimes even molecule that has a charge because it lost or gained an electron, usually from bonding.

The electronic configuration of many ions is that of the closest noble gas to them in the periodic table. An anion is an ion that has gained one or more electrons, acquiring a negative charge. A cation is an ion that has lost one or more electrons, gaining a positive charge.

Positively charged ions are called cations; negatively charged ions, anions.
62635
Polyatomic ions are ions that are composed of two or more atoms that are linked by covalent bonds, but that still have a net deficiency or surplus of electrons, resulting in an overall charge on the group. A metal plus a polyatomic ion yields an ionic compound.
591897
polyatomic ions form ionic compounds just like simple ions would . a polyatomic ion, also known as a molecular ion, is a charged species (ion) composed of 2 or more atoms covalently bonded or of a metal complex. A polyatomic ion is also considered a free radical . polyatomic ions are anions or cations.

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.

ionic equation: An equation in which dissolved ionic compounds are shown as free ions. molecular equation: An equation in which the formulas of the compounds are written as though all substances exist as molecules.

Isotopes are atoms that have the same numbers of protons but different numbers of neutrons. An ion is an atom that has gained or lost electrons, so it now has more or fewer electrons than it does protons. So an ion has a negative or positive charge.
179986
An ion is formed by the loss or gain of electrons by an atom, so it contains an unequal number of electrons and protons. Example: Sodium ion Na+, magnesium ion Mg2+, chloride ion Cl–, and oxide ion O2–. There are two types of ions : cations.

Polyatomic ions are ions which consist of more than one atom. ... The atoms in a polyatomic ion are usually covalently bonded to one another, and therefore stay together as a single, charged unit. Rule 1. The positive ion (cation) is written first in the name; the negative ion (anion) is written second in the name.
