Exploring Ionic Bonds and Their Properties

What are the two types of ions that form ionic compounds?

• Neutrons and Electrons

• Electrons and Protons

• Protons and Neutrons

• Anions and Cations

Why are ionic compounds electrically neutral overall?

• Because they have equal numbers of protons and neutrons

• Because they combine in combinations that balance each other out

• Because they are composed of only one type of ion

• Because they have no charged particles

What type of bond is formed between a positive cation and a negative anion?

• Covalent bond

• Ionic bond

• Hydrogen bond

• Metallic bond

In the example of sodium chloride, what is the ratio of sodium ions to chloride ions?

• 1:1

• 3:1

• 1:2

• 2:1

What is a formula unit in the context of ionic compounds?

• The molecular weight of the compound

• The total number of ions in a compound

• The smallest whole number ratio of ions that makes the compound neutral

• The volume of the compound

Which of the following is NOT a characteristic of ionic crystalline structures?

• They have a repeating three-dimensional pattern

• They have high melting points

• They are formed by the attraction of oppositely charged ions

• They are composed of separate individual particles

What is the coordination number of sodium chloride?

• 4

• 6

• 8

• 10

In the context of ionic compounds, what does the term 'coordination number' refer to?

• The number of oppositely charged particles around each ion

• The number of ions in a formula unit

• The number of protons in the nucleus

• The number of electrons in the outer shell

Why can ionic compounds conduct electricity when melted or dissolved in water?

• Because they have free electrons

• Because they are composed of neutral particles

• Because they have charged particles that can move

• Because they have a high melting point

What happens to the charged particles in molten sodium chloride?

• They move to the anode and cathode

• They form a solid structure

• They become neutral

• They lose their charge
