Bonding

Question 1

How do ions form

Answer 1

When one or more electrons are transferred from one atom to another

Question 2

What are the + and - ions for each group

Answer 2

Group one - +1 ions
Group 2- +2 ions
Group 6 - 2- ions
Group 7 - 1- ions

Question 3

What are the properties of ionic compounds

Answer 3

Conduct electricity when molten or dissolved as the ions are free to move and carry a charge
High melting points - Strong electrostatic forces - takes a lot of energy to overcome
Dissolve in water - water molecules are polar so the charges parts pull ions away from the lattice
