Bonding in Chemistry
Ionic, Covalent, and Metallic
bonding
Bond Formation
•
The positive sodium ion and the negative
chloride ion are strongly attracted to
each other.
•
This attraction, which holds the ions close
together, is a type of chemical bond called
an
ionic bond
.
Bond Formation
•
The compound sodium chloride, or table
salt, is formed.
•
A
compound
is a pure substance containing
two or more elements that are chemically
bonded.
More Gains and Losses
•
Can elements lose
or gain more than
one electron?
•
The element
magnesium, Mg,
in Group 2 has two
electrons in its
outer energy level.
•
Magnesium can lose these two electrons and
achieve a completed energy level.
More Gains and Losses
•
Some atoms, such as oxygen, need to gain
two electrons to achieve stability.
•
The two electrons released by one
magnesium atom could be gained by a
single atom of oxygen.
•
When this happens, magnesium oxide
(MgO) is formed.
Convalent Bonds—Sharing
•
Some atoms are unlikely to lose or gain
electrons because the number of electrons
in their outer levels makes this difficult.
•
The alternative is sharing electrons.
The Convalent Bond
•
The chemical bond that forms between
nonmetal atoms when they share electrons is
called a
covalent
bond

The Convalent Bond
•
Shared electrons are attracted to the nuclei
of both atoms.
•
They move back and forth between the
outer energy levels of each atom in the
covalent bond.
•
So, each atom has a stable outer energy
level some of the time.
The Convalent Bond
•
The neutral particle is formed when atoms
share electrons is called a
molecule
The Convalent Bond
•
A molecule is the basic unit of a molecular
compound.
