CHEMICAL BONDS - Ionic Chapter 6
2
6.1 BONDING - journal Begin filling in the table on the top of the Bonding Basics – Ionic Bonding Worksheet.
3
Chemical PROPERTIES depend on the number of valence electrons.
6.1 BONDING Chemical PROPERTIES depend on the number of valence electrons.
4
6.1 BONDING Therefore, chemical bonding and reactivity depend on an element’s electron configuration.
5
6.1 BONDING STABLE ELECTRON CONFIGURATION:
Which group does this describe?
6
What do elements with UNSTABLE ELECTRON CONFIGURATIONS do?
6.1 BONDING What do elements with UNSTABLE ELECTRON CONFIGURATIONS do?
7
They BOND and form compounds
6.1 BONDING They BOND and form compounds IONIC BONDING
8
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 Both Sodium and Chlorine are now STABLE in their highest energy levels
9
What types of elements are Sodium and Chlorine?
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
When an atom gains or loses electrons, what does it get?
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
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 WHAT DO OPPOSITE CHARGES DO?
16
This is when the IONIC BOND forms.
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.
19
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
20
6.1 IONIC BONDING PROPERTIES OF IONIC COMPOUNDS
Form between a metal and a nonmetal Brittle/crystalline High melting/boiling points Dissolve (ions come apart) in water & conduct electricity
21
6.1 IONIC BONDING NAMING IONIC COMPOUNDS NaCl – Sodium Chloride
HF – Hydrogen Fluoride MgI2 – Magnesium Iodide KBr - ??? Potassium Bromide This is Binary Nomenclature Ionic Bonding Challenge
22
IONIC BONDING POLYATOMIC IONS
Sometimes groups of atoms can have a positive or negative charge. COMMON POLYATOMIC IONS NH4+ – Ammonium NO3- – Nitrate OH1- - Hydroxide CO32- – Carbonate SO42- - Sulfate PO42- - Phosphate
23
NAMING COMPOUNDS WITH POLYATOMIC IONS
6.1 IONIC BONDING NAMING COMPOUNDS WITH POLYATOMIC IONS CaCO3 Calcium carbonate HNO3 Hydrogen nitrate (nitric acid) NH4Cl Ammonium chloride NaOH Sodium hydroxide
