Ionic Bonding and Compounds Flashcards
1
Q
definition of ionic bonding
A
transfer of electrons between a metal and non-metal. the oppositely charged ions are strongly attracted to each other by electrostatic attractions = ionic bonds
2
Q
how to work out the formula of an ionic compound
A
crossover method
3
Q
ionic compounds have …
A
- giant ionic lattice structures
- the ions are held together in a closely packed 3D lattice arrangement
- high melting and boiling points = lots of energy needed to overcome the strong electrostatic attraction
- only conduct electricity when melted or dissolved
