Covalent bond Ionic bond
• Covalent bond doesn’t conduct electricity because it is a sharing of electrons and they don’t have any free ions. That’s why they don’t conduct electricity.
• They have low melting and boiling point because they don’t have strong intermolecular forces and atoms are not very strongly held together. That’s the reason they have less boiling and melting point.
• They are not dissolve I water means they are not electrolytes because non-polar molecules don’t dissolve in water.
• Many occur as liquid or gases because of weak intermolecular forces. When it’s polar then it’s likely to be solids or liquids because molecules attract each other. When it’s non-polar then it more likely to be gas because partials are spread

Ionic compounds are made up of ions which have electrostatics attraction that hold ions together. They also form a crystal metals.
• They are dissolve in water because their one end is partial positive and the other is partial negative and they both attract each other.
• They are brittle.

Giant ionic, giant molecular and one
Simple molecular substance:
Giant ionic Giant molecular Simple molecular
Giant ionic is define as when Large number of atoms combine and transfer their electrons and make a giant ionic bond. These substances are called giant ionic.
They are very strong and have strong intermolecular force of attraction between the molecules and it’s hard to break them.
For example: NaCl formed into a giant ionic structure, which is also known as lattice arrangements.
Lattice arrangement is something where positive ions is surrounded by the negative ions and vice versa.
Na is surrounded by Cl and Cl is surrounded by Na because Na has positive charge and Cl has negative charge. Giant molecular is also called as giant covalent. Giant molecular compounds, have a lot of non-metals atoms, they are joined together and share their electrons.
Atoms are arranged into giant regular

It happens between non-metals. The intermolecular forces are not strong in molecular boding but has strong intramolecular forces (forces between atoms). That is why they are easy to break.
It is called simple molecular or covalent substance.

Properties of giant ionic, giant molecular and simple molecular substances.
Giant ionic Giant molecular Simple molecular
• High melting and boiling point: They have high melting and boiling points and the reason is because they have a strong ionic bond and it’s a giant structure, so they have many bonds and have strong force of attraction. Large amount of energy requires to break them down.
• Can dissolve in water, because ionic compounds are made up of ions and these ions can interact with water.
• Can conduct electricity when they are in liquid state; not in solids because they don’t have free ions. • High melting and boiling point: They high melting and boiling points because they have strong intermolecular forces between the atoms and have a lot of bonds between and its takes a lot of energy to break these bonds. That’s the reason they have high melting and boiling
