Ionic+Bonding.

__ Ionic Bonding __ =__How does this occur?__ = Ionic bonding occurs in a metal and non-metal atom. It involves a =__ How ions form __ =  Ions are electrically charged particles formed when atoms lose or gain electrons. This loss or gain leaves a complete highest energy level, so the electronic structure of an ion is the same as that of a noble gas - such as a helium, neon or argon. Metal atoms and non-metal atoms go in opposite directions when they ionise:

 Positively charged ions are represented with a small plus symbol next to the element e.g. Negatively charged ions are represented by a small minus sign next to the element e.g.
 * **Metal atoms** lose the electron, or electrons, in their highest energy level and **become positively charged ions**.
 * **Non-metal atoms** gain an electron, or electrons, from another atom to **become negatively charged ions**.
