Chem: Ions and Ionic bonds

Define Ions

These are charged atomes formed by either the loss or gain of electrons

Define Ionic bonds

Strong electrostatic forces of attraction that act between oppositely charged ions to keep the intact.

Define ionic bonding

When metals and non metal share electrons to bond together .

Define Cations

+ions

Define anions

-ions

Properties of ionic compounds

1. High M.P and B.P

2. conduct electricity when molten or aqueous

3. soluble

4. solids at room temp

explain why ionic bonds have high M.P and B.P

they have strong electrostatic between them therefore requireing more energy to break them.

Explain why ionic bond Conduct electricity only in molten or aquoeuse form?

the ions are closely packed together so current cannot pass throught to allow current to pass the ions have to be more free so you either heat them until they are a liquid or you dissolve them.

Explain why ions are soluble

the postive and negative ions are attracted to water

Explain why they are solids at room temp

They have strong electrostatic forces bewteen hem thereofre they require more energy to break them.
