What is ion?🧐

• Ions are charged particles which are made when electrons are transferred. 
• When metals form ions, they lose electrons and become positively charged.
• When non-metals form ions, they gain electrons and become negatively charged.
• The number of electrons either gained or lost is the same as the charge.
• The elements in groups 1,2,6 and 7 are the most likely to form ions.The elements in groups 1 and 2 are metals and they therefore lose electrons to form positive ions, +1 and +2.The elements in groups 6 and 7 are non-metals and they therefore gain electrons to form negative ions, -2 and -1.

For I/GCSE Chemistry, it is crucial to know how to form ionic bond from ions

1. Ionic bonding occurs when a metal and a non-metal react together.
2. The metal loses its electron and the non-metal gains that electron.
3. When they react, the two opposite charges are attracted and they form an ionic bond

👇Here is an example of an ionic compound formed from a sodium ion and a chloride ion👇

That's the end of ionic bond.
