What kinds of bonds?

IONIC Bond

-  an electrostatic interaction that holds together a positively charged (cation)

and a negatively charged ion (anion)

How the ionic bond is formed?

1. state the elecron arrangement of atom

2. how much of elecron that the atom donates

3.Which atom will receive electron

4.state the purpose of ionic bond

5.what force attract the ions

6. Formation of what bond.

Eg.

MAGNESIUM OXIDE, MgO

1. Electron arrangement of atom Mg;2.8.2

     Electron arrangement of atom O:2.6

2.Atom Mg donates 2 electron

3.Atom O receives 2 electron

4.To achieve an octet arrangement

5.Attraction force between Mg2+ and O2- to form MgO

6.Ionic bond is formed
