3
6.1 BONDING

• Chemical PROPERTIES depend on the number of
  valence electrons.

4
6.1 BONDING

• Therefore, chemical bonding and reactivity depend
  on an elements electron configuration.

5
6.1 BONDING

• STABLE ELECTRON CONFIGURATION
• Which group does this describe?

6
6.1 BONDING

• What do elements with UNSTABLE ELECTRON
  CONFIGURATIONS do?

7
6.1 BONDING

• They BOND and form compounds
• IONIC BONDING

8
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

9
6.1 BONDING

• IONIC BONDING the forming of a stable electron
  configuration through electron transfer
• What types of elements are Sodium and Chlorine?

10
6.1 BONDING

• IONIC BONDING the forming of a stable electron
  configuration through electron transfer between a
  metal and a nonmetal.

11
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.

12
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.

13
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).

14
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

15
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?

16
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.

17
6.1 BONDING

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

18
6.1 IONIC BONDING

• Ionization Energy the ability to PULL ON
  ELECTRONS.
• Which side has the MOST PULL?
• Which side GIVES UP electrons more easily?

Look at Data Analysis at the top of page 160.
