Ions are electrically charged particles. They form when an atom contains an unequal number of protons in the nucleus and electrons in the electron cloud. Of course, there should be neutrons in the nucleus too but that makes no difference since neutrons are neither -1e or +1e but are electrically neutral.Since protons are positively charged and electrons are negatively charged, if there are more electrons than protons, the atom or molecule will be negatively charged. This is called an anion.Conversely, if there are more protons than electrons, the atom or molecule will be positively charged. This is called a cation. GOOD LUCK.

Atoms which have the same number of electrons and protons. They are electrically charged particles that have lost or gained an electron from an atoms valence shell. When ions are missing an electron they are positively charged (ciation) and when they have an extra electron they carry a negative charge (anions) Ions "borrow" electrons thus creating an ionic bond.

Ions are formed when a electrically neutral atom either gives away or accepts electrons. They can be positive or negative.
An atom or molecule with a net electric charge due to the loss or gain of one or more electrons.

An ion is 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. The valence by an ion is equal to the number of electrons lost or gained and is indicated by a plus sign for cations and a minus sign for anions.

an atom that has lost or gained electrons to form a full outer shell, if it combinds with another atom so both get a full outer shell you use the term ionic bonds

A ion is a atom or molecule. This is when electrons is not equal to the total number of protons.
