What is a covalent bond?
Catalyst
Atoms ___________ one or more electrons with each other to form the bond.
Each atom is left with a ________________ outer shell.
A covalent bond forms between two _________________.

LECTURE 2.4 – METALLIC BONDS
WHAT ARE METALLIC BONDS?
Today’s Learning Target
•LT 2.5 – I can define a metallic bond and
explain the role of electrons in the formation of
these bonds.

Bonds
I. Metallic Bonds
•This is a bond between multiple metal atoms
•Only involves valence electrons
•Forms between many metal atoms, so
electrons are free to jump between atoms.
•Therefore, valence electrons can be transferred
with little to no work
II. “Sea of Electrons”
•This ability to roam creates a “sea of electrons”
within a metallic bond
•This means that heat and charge can be easily
passed between multiple atoms in a metallic
bond.
•This is why metals are good conductors
The core of the planet Jupiter could be said to be
held together by a combination of metallic bonding
and high pressure induced by gravity.
HOW DO YOU IDENTIFY COMPOUNDS AS
IONIC, COVALENT OR METALLIC?
I. Identifying Compounds
•If it is made of a metal and a non-metal, then it
is an ionic
•If it is made of only non-metals, then it is a
covalent.
•If it is made of only metals, then it is metallic.

Practice Benchmark Quiz Thurs/Fri
•You will have 40 minutes to complete the
multiple choice benchmark
•This should be done without notes and should
be completed silently. Study to get ready!
Closing Time
• Study the different chemical bonds and their
criteria! You’re gonna ace this test 
