Multiple Choice

What type of forces hold on an ionic lattice together?

• Electrostatic attraction forces

• Covalent bond

• Metallic bond

• Van der Waals forces

Multiple Choice

The reason that a sodium atom bonds with a chlorine atom is because

• Sodium transfers an electron to Chlorine
• oppositely charged ions form a strong electrostatic attraction
• ions are the same size
• the ions have a full outer shell

Multiple Choice

• Ionic

• Covalent

Multiple Choice

Which two compounds are ionic?

• compound E

Multiple Select

Magnesium oxide is insoluble in water. Can magnesium oxide conduct electricity?

Select yes or no and a reason.

• Yes

• No

• Magnesium oxide can be heated so that it melts and conducts electricity.

• Magnesium oxide doesn't dissolve, so it stays in its solid state and doesn't conduct electricity.

Multiple Choice

Why do ionic compounds conduct electricity when they are molten or dissolved?

• Their ions are free to move.

• Their ions are held in fixed positions.

• Their electrons are free to move

• Their electrons are held in a fixed state

Multiple Choice

Why do ionic compounds NOT conduct electricity when they are in their solid state?

• Their ions are free to move.

• Their ions are held in fixed positions.

• Their electrons are free to move

• Their electrons are held in a fixed state

Multiple Choice

True or false? Ionic compounds conduct electricity when they are in their solid state.

• true

• false

Multiple Choice

Which of the following is NOT TRUE about covalent compounds?

• They have low melting and boiling points.

• They are formed from 2 nonmetals.

• They can conduct electricity when dissolved in water (aqueous).

Multiple Choice

Ionic compounds conduct electricity when dissolved in water. Which statement below best explains the property?
