What happens to electrons in ionic bonding?

They are transferred from one element to another.

What type of elements form ionic compounds?

A metal with a nonmetal

In the formation of ionic compounds, which type of element gets oxidized and which gets

reduced?

Generally a metal will lose electrons (get oxidized) and form a cation and a nonmetal will gain

electrons (get reduced) and form an anion.

Ionic compounds are composed of what type of particles?

Oppositely charges ions.

What is the attractive force holding ionic compounds together?

The electrostatic attraction between the oppositely charged ions. (Coulomb’s Law)

List 5 properties of ionic compounds.

1. Brittle

2. Do not conduct electricity in the solid state. 3. Will conduct electricity when

melted or dissolved into water. 4. High Melting point.

5. Many are soluble in water because

the there is a strong attraction between the very polar water and the ions.

Why are ionic compounds brittle?

In an ionic crystal, each positive ion is completely surrounded by negative ions and vice-versa.

When hit, the ions are forced to move causing positive to get next to positive and negative next to

negative. Since like charges repel, the crystal breaks apart.

Why can't ionic solids conduct electricity in the solid state?

Electricity is the flow of charged particles. Although ionic solids contain charged particles, the

ions are held rigidly in place in the crystalline structure, therefore, they cannot move or flow

which means they cannot conduct electricity.

When can ionic solids conduct electricity" Why?

Ionic compounds can conduct in the melted or aqueous states because in these states the bonds

holding the ions together are broken so they are now free to move which means they can conduct

electricity.

10. What is electricity?

The flow of charged particles.

11. Describe metallic bonding.

Metallic bonding only occurs between atoms of the same element (metal). In the metallic crystal,

each metal cation is surrounded by a “sea of free-flowing valence electrons”. The bond holding

the atoms together is the attraction between the positive metal cations and the valence electrons

in between

them.
