Chemistry - ionic bonding

How are ions formed?

By atoms gaining or losing electrons.

What happens when a metal forms an ion?

It loses electrons and forms a positive ion.

What happens when a non–metal forms an ion?

It gains electrons and forms a negative ion.

What charge do Group 1 metals form?

+1.

What charge do Group 2 metals form?

+2.

What charge do Group 3 metals form?

+3.

What charge do Group 5 non–metals form?

What charge do Group 6 non–metals form?

What charge do Group 7 non–metals form?

What is the charge on a silver ion?

Ag⁺.

What is the charge on a copper(II) ion?

Cu²⁺.

What is the charge on an iron(II) ion?

Fe²⁺.

What is the charge on an iron(III) ion?

Fe³⁺.

What is the charge on a lead(II) ion?

Pb²⁺.

What is the charge on a zinc ion?

Zn²⁺.

What is the charge on a hydroxide ion?

What is ionic bonding?

The strong electrostatic attraction between oppositely charged ions.

Why do ionic compounds have high melting and boiling points?

Strong electrostatic forces between ions require a lot of energy to overcome.

Why do ionic compounds not conduct electricity when solid?

The ions are fixed in place and cannot move.

Why do ionic compounds conduct electricity when molten or dissolved?

The ions are free to move and carry charge.

What is an ionic lattice?

A giant three – dimensional structure of alternating positive and negative ions.
