Ionic Bonds
Definition: A type of chemical bond that involves the electrostatic attraction between two oppositely charged ions
-cation, anion
- 1 metal, 1 non-metal
Example:
-NaCl
-BeS
Covalent Bonds
Definition: A chemical bond that involves the sharing of electron pairs between atoms.
-Polarity
-Polar Covalent Bond
-Examples:
- H2
-HCl
-H2O
Explore the Bonds
- 15 minutes with each envelope pack
- work in pairs to complete task
- both partners names and date must be on answer sheet

TOD
1) _________ bonds occur between two non-metals and is when two atoms share an _______.


2) An ______bond is due to electrostatic attraction between two ions.
Mind/Matter
-Using all of the aspects of the periodic table that we've discussed so far what do you think an ionic bond is? How may ionic bonds be similar/different from covalent bonds? Can you explain how each bond happens?
-List the three formulas for finding protons, neutrons and electrons.
BELLWORK
- Take out a pen or pencil and a scratch sheet of paper
- go to kahoot.com
- be patient

BELLWORK

- Draw the Lewis dot diagram for Li (lithium) and the Bohr Model for Cl (chlorine)

MID-TERM EXAM
