Ion-estly do not share but I’m neutral about it

2. Bonds are attractions between 2 or more atoms
Certain elements are more likely to bond than others.
Why does this occur?

3. Bonds are attractions between 2 or more atoms
Certain elements are more likely to bond than others.
Why does this occur?
Number of valence electrons
Energy levels 2 and above prefer 8 e- AKA Octet Rule
Attractions from protons and e- cause the e- to transfer

4. ION – Transfer of Electrons
Charged atom
Negative (gain an e-ANION)
Positive (loose an e-CATION)
Atoms transfer an electron to another
Results in dropping of an energy level and developing a charge

5. ION – Charged stability
Most common COMPOUNDS are formed by the transferred e- from GROUP 1.
Which group would these elements most likely join with?
GROUP 7 because their valence shell is nearly complete reaching STABILITY!
Draw and example
Draw electron dot diagrams for the following compounds include the charges in the chemical formula
NaCl KI P

6. Practice
Identify the number of valence e- for each element in the chemical formula
Which element will transfer its e-
Create an electron dot diagram for each compound
Include the charges of the ions
NaCl KI

7. ION – Charged stability
Most common COMPOUNDS are formed by the transferred e- from GROUP 1.
Which group would these elements most likely join with?
GROUP 7 because their valence shell is nearly complete reaching STABILITY!
Draw electron dot diagrams for the following compounds include the charges in the chemical formula
Na+Cl-
K+I-
Circle and highlight positive and negative ions
What is the total charge (net charge) of the compound? P

8. IONIC BOND When an atom looses or gains an e- The atom becomes charged
The new negative and positive charge of the atoms causes them to be attracted to one another
Overall net charge of zero
Usually formed between metals and non-metals across the periodic table

Recap
Some elements develop stability by teaming up with other elements
Octet rule
Ions – do not share e-, give or take AKA transfer e-
Likely to happen between metals and non metals
After the transfer of e-, atoms are attracted to one another due to their new charge
Negative (gain an e-ANION)
Positive (loose an e-CATION)
