What elements ionically bond
Non metals and metals
What elements covalently bond
Non metals
What property do substances have when they have stronger forces between there particles
High melting and boiling point
What does ionic bonding form?
Giant ionic structure
What is ionic bonding
The transferring of electrons to gain a full outer shell.
What state are ionic compounds at room temperature
Solid
Why are ionic compounds solid at room temperature
Many strong electrostatic forces hold the oppositely charged ions together
What is the melting and boiling point for a ionic compound
High
What happens when ionic compounds melt
The ions are free to move so the liquids can conduct electricity
What is a substance held together by covalent bonds called
Molecules
What do many covalent bonds consist of
Small molecules
What is a covalent bond
Sharing electrons between atoms.
What do substances made of simple molecules have
Low melting and boiling points
Are covalent bonds strong?
Strong
What are the forces between molecules called
Intermolecular forces
What are the forces between molecules like
Weak
What happened when a molecule increases in size
Intermolecular forces increase and so have higher melting and boiling points
Why Do simple molecules conduct electricity
There is no overall charge on the simple molecule
What is diamand
A giant covalent structure
When do intermolecular forces increase
When the size of the molecule increases
In graphite how many electrons are delocalised
