1. Ionic BONDING

2. Happiness…… Everyone wants to be happy.. What makes an atom happy?!
Atoms are no different.
What makes an atom happy?!

3. OCTET!! OCTET: 8 valence electrons
Atoms will lie, cheat and steal to achieve an octet.
aka: atoms share electrons, take electrons and give electrons to have 8 valence electrons

4. FOCUS ON THE GIVERS and TAKERS
When giving/taking is involved it is called ionic bonding.
Ionic Bonding: when atoms gain or lose electron(s) to form a chemical bond

5. GIVERS
Who gives?!

6. TAKERS
Who takes?!

7. GIVERS/TAKERS Left side – givers (metals)
Right side – takers (non-metals)

8. PUTTING IT TOGETHER: Lewis dot structures:
Shows the number of valence electrons
Shows the number of unpaired electrons
Shows the number of lone pairs electrons
Shows where bonds can happen

9. DOT STRUCTURE Rules: Write the chemical symbol of the element
Determine the number of valence electrons
Divide the symbol into 4 sides
Place one electron on each side before adding a second

10. What happens to the charge when atoms take/give or gain/lose?
Take/Gain
negative charge
anion
Give/Lose
positive charge
cation

11. Draw the Lewis Dot Structure and determine the charge.Na F S Ca Al N
