Ionic Bonding is the ....
Transfer of electrons
1 of 12
Explain Ionic Bonding
Atoms lose or gain electrons to form charged particles (ions) which have a strong electrostatic attraction between them - gives ionic compounds high melting and boiling points
2 of 12
What is oxidation?
When an atom loses electrons
3 of 12
What is reduction?
When an atom gains electrons
4 of 12
