IONIC BONDING: Metals and Non Metals
- It is between a metal and a non metal
- Metal loses an electron and become positively charged.
- Non- Metal gains an electron and becomes negatively charged.
- There is a strong electrostatic force of attraction between opposite charged ions resulting in ionic bonding.

PROPERTIES OF IONIC COMPOUNDS
Ionic Compound Properties
- Brittle solids with definite crystal shapes
In Ionic compounds, there is a strong electrostatic force of attraction between the opposite charged ions. This results in the formation of giant ionic lattice.
- Good insulators in solid form, but become good conductors in liquid or dissolved form.
In the solid form, the ions are not free to move as they are held together by strong electrostatic force of attraction. In molten or when they are dissolved in water the ions are free to move and conduct electricity.
- High melting and boiling point compared to molecular compounds
In Ionic compounds, there is a strong electrostatic force of attraction between the opposite charged ions. This results in the formation of giant ionic lattice. Large amount of energy is required to overcome the strong electrostatic force of attraction. Therefore, ionic compounds have high melting and boiling point.
Greater the charge of an ionic lattice, stronger is the electrostatic force of attraction. Greater the melting and bp.
For éx – Aluminium chloride > Magnesium chloride > sodium chloride

| Hydroxide = OH– |
COVALENT BONDING
- It is between two non metals
- It involves the sharing of electrons between two non metals.
- More than one electron pair can also be shared resulting in the formation of single double and triple bonds.
Bonding Structure and properties
Properties of Covalent Compounds
Simple Molecule
- Eg – O2, CH4
- They have weak intermolecular forces in them so have a lower melting and a boiling points
- The intermolecular forces increases with increase in size as the surface area between the molecules increases.
- Therefore, polymers which have covalent bonding between them have high melting and boiling point due to increase in chain length.
Giant Covalent
- Diamond
- Graphite
- Silicon Dioxide
GIANT COVALENT STRUCTURES
Substances which have huge network of atoms joined together by covalent bonds form giant covalent structures.
DIAMOND GRAPHITE It is hard. It is soft and greasy. It is an insulator It is a conductor It has a high density. It has a lower density than diamond. Each carbon atom is covalently bonded to four other carbon atoms giving it a strong rigid structure Carbon atoms are bonded in the form of layer in the form of hexagons. No covalent bonding between the layers so they can slide past. Each carbon atom is bonded with three other carbon leaving the fourth electron has delocalized No delocalised electrons present It has delocalised electrons Used in cutting or jewellery It is used in pencil leads.
PROPERTIES OF GRAPHITE
Q1 Why graphite is soft and slippery?
Banner 5
In graphite, Carbon atoms are bonded in the form of layers in the form of hexagons. No covalent bonding between the layers so they can slide past each other. The layers have only weak intermolecular forces between them. By applying a little pressure then layers can easily slide past each other making Graphite soft and slippery.
Q2 Why graphite conduct electricity ?
In graphite, Carbon atoms are bonded in the form of layer in the form of hexagons. No covalent bonding between the layers so they can slide past. Each carbon atom is bonded with three other carbon leaving the fourth electron has delocalized. These delocalized electrons are mobiles electrons which can move and conduct electricity.
FULLERENE AND GRAPHENE
Fullerene: Hollow shaped molecule having hexagonal rings like a bucky ball.
- Also known as bucky ball or buckminsterfullerene.
- Carbon can be in the form of pentagon or hexagon rings
- Used as catalyst, drug delivery and treating cancer.
- Graphene: Layer of interlocking hexagonal rings like single sheet of graphite.
- It is a better conductor than graphite, light and have low density.
- Used in making computer chips and flexible electronic displays.
Baneer 6
CARBON NANOTUBES
- Cylinderical fullerene with the length greater than the diameter.
- High tensile strength – Used in making reinforced composite materials
- High electronic conductivity – used in electronic industry
METALLIC BONDING
- It is between two metals.
- There are fixed positive ions present in the sea of delocalised electrons.
- There is strong electrostatic force of attraction between fixed positive ions and delocalized electrons resulting in metallic bonding.
Banner 8
Properties of Metals
Metals are malleable
- Malleable means that the metals can be hammered into any shape.
- Metals have layered structure and layers can slide past each other by hammering giving metals different shapes.
Metals are ductile
- Ductile means that the metals can be drawn into thin wires.
- Metals have layered structure and layers can slide past each other by hammering giving metals a wire shape.
Metallic Bonding
- Atoms in a metal are arranged in a regular manner and vibrate about fixed positions.
- The outermost electrons move freely, forming a ‘sea of electrons’ enveloping the positive metal ions.
Metals are good conductors of electricity
- Metals have delocalised electrons.
- They are mobile and conduct electricity.
- These mobile electrons or delocalised electrons conduct heat and electricity.
Metals have high melting and boiling points
- There is strong electrostatic force of attraction between fixed positive ions and delocalized electrons.
- Large amount of energy is required to overcome strong electrostatic force of attraction.
Banner 9
ALLOYS
- Alloys are the mixture of metals with another metal or a non metal which make the metal stronger.
- In metals the particles are arrranged in layers. There is a regular arrangement of fixed positive ions which can slide past each by applying pressure.
- In alloys there is a mixture of metals with another metal or a non metals. Another metal being different in shape and size distort the regular arrangement of the metal lattice.
- As a result the layers of the metal can no longer slide past each other making it strong
Example: Steel is the alloy of iron which is more strong and resistant to corrossion.
NANOPARTICLES
Nanoparticles are the particles that deals with the paricles of size 1 to 100 nm.
KIL- Killing
MET – Metal
MIL -Milo
MIC – Mickey
NAN – Nano
PIC – Pictures
Convert 10 nm to
- Metre = 10/109m = 10-8m
- Micrometer = 10/106m = 10-5m
SURFACE AREA TO VOLUME RATIO
As the size decreases the surface area to volume ratio Increases.
Therefore Nano particles being very small in size have large surface area to volume ratio making them very useful in Science and Medicine.
Surface area = 6 x side x side m2
= 6 x 1000 x 1000
= 6 106 m2
Volume = side x side x side
= 109m3
SA: Volume = 6 x 106/109 = 6 x 103 m
Surface area = 6 x side x side m2
= 6 x 1000 x 1000
= 6 104 m2
Volume = side x side x side
= 106m3
SA: Volume = 6 x 102 m
