Chapter 6, Section 2: Ionic and Covalent Bonding
I. Why do chemical Bonds form?
a. Atoms bond when their __________________________ interact.
b. Atoms join to form bonds so that each atom has a stable _______________
configuration.
c. copy figure one below (from page 183)
II. Ionic Bonds
a. Ionic bonds form from the attractions between such
______________________ charged particles.
b. Ionic bonds occur between ___________ and ____________________.
c. Ionic bonds are formed by the ____________________ of electrons
d. Ionic compounds are in the form of ______________________
e. When melted or dissolved in water, ionic compounds ____________________
III. Covalent Bonds
a. made of ______________________
b. electrons are ______________________
c. can be ____________, ___________________, or __________________
d. Molecules are _________ to move when dissolved in a liquid but they do not
conduct electricity because the molecules are not _____________.
e. ___________________________________ electrons are shared equally
f. ____________________________________ electrons are NOT shared equally
Let’s draw some examples of Covalent bonds.
Let’s start with SINGLE COVALENT BONDS – SHARE 2 ELECTRONS!
Remember the octet rule!
Cl2
Some can be DOUBLE COVALENT BONDS = SHARE 4 ELECTRONS
02
Some can be TRIPLE COVALENT BONDS === SHARE 6 ELECTRONS
N2
IV. Metallic Bonds
Explain how electrons behave in metals.
Why do metals conduct electric currents so well.
V. Polyatomic Ions
List a couple of Polyatomic Ions. Give name and Formula (make sure to include
charge!)
Why are parentheses used?
