Q
How do you describe the electron transfer
A
- Movement of the electrons
- Changes in the charges
- Electronic configuration

Q
Why do ionic compounds have a high melting and boiling point
A
Electrostatic attraction is very strong because a lot of energy is needed to overcome the strong attraction
