ion•atom or group of atoms that has an electric charge

• Much like people, most atoms don't like to live solitary existences.
• They need to COME TOGETHER with other atoms to lead more stable, happier lives.
• This process of coming together is called chemical bonding.

ionic bond
• forms a neutral ionic compound
• the 2 atoms then become oppositely charged ions & feel a strong electric attraction for each other
• formed between 2 atoms of a molecule when 1 atom transfers valence electrons to the other

Ionic bonding:Ionic bonding: In the playground at recess, a 3rd grader has a chocolate bar. A 7th grader takes the chocolate bar from the 3rd grader and the 3rd grader follows the 7th grader around for the rest of the recess, trying to get some of it back.
This is like a BIG Cl atom taking a little Li’s electron to make LiCl.

The animation shows the process that takes place during the formation of an ionic bond.

One electron is transferred from the sodium atom to the chlorine atom.
![Page 15: 8th Grade-Ch. 1 Sec. 3 Ionic Bonds](https://reader038.fdocuments.us/reader038/viewer/2022102815/55507c39b4c905cc0f8b54eb/html5/thumbnails/15.jpg)
After losing an electron, the sodium atom becomes a sodium ion with a 1+ charge.
After gaining an electron, the chlorine becomes a chloride ion with a 1- charge.

Naming ionic compounds1. Name of positive ion (usually a metal)
2. Name of negative ion– if negative ion is an element- end of
its name changes to –ide– if negative ion is polyatomic- name
remains unchanged – example: Sodium
Bicarbonate
NaHCO3
