• 1.4 How does Ionic Bonding Work?

AIM How does ionic bonding work and how can we
tell it happened??
DO NOW
Draw the Lewis Structure for Calcium How many
electrons does Calcium want to gain or lose
? Write the ion that is formed (dont forget
the charge!). Why does an ion have a
charge? Does the radius of this Calcium ion
increase of decrease?

BOND. CHEMICAL BOND
YOUR DEFINITION
Only the chemist can tell, and not always the
chemist, What will result from compounding Fluids
and solids. And who can tell How men and women
will interact On each other, or what children
will result? There were Benjamin Pantier and his
wife, Good in themselves, but evil towards each
other He oxygen, she hydrogen, Their son, a
devastating fire. -- Edgar Lee Masters, Spoon
River Anthology Ca 1916

COMPLETE A READING
DIRECTIONS Read the passage and watch the videos
to Develop your own definition of each type of a
bond.
OUR DEFINTIONS
IONIC BONDING COVALENT BONDING

Bonds that are formed between ions due to
TRANSFER OF ELECTRONS
Bonds that are formed between atoms due to
SHARING OF ELECTRONS

• OUR DEFINTIONS

Between metal and a nonmetal
Between two nonmetals
Conduct electricity when dissolved in solution
Usually liquid or a gas

HOW DO WE BOND ATOMS?
CRISS-CROSS RULE
Method that helps us determine what
compounds form when atoms bond.
