6.1 BONDING

Chemical PROPERTIES depend on the number
of valence electrons.
6.1 BONDING

Therefore, chemical bonding and
reactivity depend on an element’s
electron configuration.
6.1 BONDING

STABLE ELECTRON CONFIGURATION:

Which group does this describe?
6.1 BONDING

What do elements with UNSTABLE ELECTRON
CONFIGURATIONS do?
6.1 BONDING
They BOND and form compounds

IONIC BONDING – the forming of a stable
electron configuration through electron
transfer
Both Sodium and Chlorine are now STABLE in
their highest energy levels


IONIC BONDING – the forming of a stable
electron configuration through electron
transfer
What types of elements are Sodium and
Chlorine?
6.1 BONDING

IONIC BONDING – the forming of a stable
electron configuration through electron
transfer between a metal and a nonmetal.


IONIC BONDING – the forming of a stable
electron configuration through electron
transfer between a metal and a nonmetal.
When an atom gains or loses electrons, what
does it get?
 A CHARGE.
6.1 BONDING

IONIC BONDING – the forming of a stable
electron configuration through electron
transfer between a metal and a nonmetal

ION: An atom with a positive or negative
CHARGE from electron transfer.
6.1 BONDING

IONIC BONDING – the forming of a stable
electron configuration through electron
transfer between a metal and a nonmetal
In the bond, one becomes positive (loses
electrons) and one becomes negative (gains
electrons).


Positive Ion (loses electrons): Cation
Negative Ion (gains electrons): Anion

HOW can you predict which elements will
make positive cations and which will make
negative anions?

Ionization Energy: the ability to PULL ON
ELECTRONS.
Look at “Data Analysis” at the top of page
