Positively charged particles inside the nucleus

Define Element
Elements are pure substances composed of only one type of atom.
Define Ion
When atoms either lose or gain electrons in a chemical reaction to achieve a full valence shell and become stable
Why do atoms lose or gain electrons to form ions?
To get a full valence shell therefore become stable
Define Ionic Compound
An electrostatic attraction between cations (+) and anions (-)
Define Ionic Bonding
When a metal and non-metal element react together, they react to form ions.
- Metal atoms lose their valence electrons to empty their outer shell
- Non-metal atoms gain the number of electrons needed to fill their outer shell
