Begin filling in the table on the top of the Bonding Basics – Ionic Bonding Worksheet.
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
6.1 BONDING
IONIC BONDING – the forming of a stable electron configuration through electron transfer
Both Sodium and Chlorine are now STABLE in their highest energy levels
6.1 BONDING
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.
6.1 BONDING
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).
6.1 BONDING
IONIC BONDING – the forming of a stable electron configuration through electron transfer between a metal and a nonmetal
Positive Ion (loses electrons): Cation
Negative Ion (gains electrons): Anion
6.1 BONDING
IONIC BONDING – the forming of a stable electron configuration through electron transfer between a metal and a nonmetal
WHAT DO OPPOSITE CHARGES DO?
6.1 BONDING
IONIC BONDING – the forming of a stable electron configuration through electron transfer between a metal and a nonmetal
ATTRACT.
This is when the IONIC BOND forms.
6.1 BONDING
HOW can you predict which elements will make positive cations and which will make negative anions?
6.1 IONIC BONDING
Ionization Energy: the ability to PULL ON ELECTRONS.
Look at “Data Analysis” at the top of page 160.
Which side has the MOST PULL?
Which side GIVES UP electrons more easily?
6.1 IONIC BONDING
Ionization Energy: the ability to PULL ON ELECTRONS.
Take out your Periodic Table.
Predict the OXIDATION NUMBERS (charges) of the ions for A Groups
