Question 1

Which of the following best describes the process of ionic bonding?

Accepted Answer

Atoms transfer electrons from one to another, resulting in oppositely charged ions that attract each other.

Question 2

What is the correct formula for the ionic compound formed between sodium (Na) and chlorine (Cl)?

Accepted Answer

$$\mathrm{NaCl}$$

Question 3

Which of the following compounds is most likely to have the highest melting point?

Accepted Answer

$$\mathrm{NaCl}$$

Question 4

Why do ionic compounds conduct electricity when dissolved in water?

Accepted Answer

The ions are free to move and carry charge.

Question 5

Which property is NOT typical of ionic compounds?

Accepted Answer

Malleability

Question 6

What is the main force responsible for the formation of ionic compounds?

Accepted Answer

Attraction between oppositely charged ions

Question 7

Which of the following best explains why ionic compounds are brittle?

Accepted Answer

The ions are arranged in a rigid lattice, and shifting layers causes repulsion between like charges.

Question 8

A student dissolves potassium bromide ($$\mathrm{KBr}) in $$water. What property will the solution exhibit?

Accepted Answer

It will conduct electricity due to the presence of free ions.

Question 9

Which of the following is a correct statement about the formation of $$\mathrm{Na^+}$$ and $$\mathrm{Cl^-}$$ ions?

Accepted Answer

Sodium loses an electron and chlorine gains an electron.

Question 10

Which of the following compounds has properties most similar to sodium chloride ($$\mathrm{NaCl}$$)?

Accepted Answer

Potassium bromide, $$\mathrm{KBr}$$

Question 11

Which of the following is NOT a consequence of the strong electrostatic forces in ionic compounds?

Accepted Answer

Softness and flexibility

Question 12

If a compound is formed by the transfer of electrons from one atom to another, what type of compound is it?

Accepted Answer

Ionic compound

Question 13

Which of the following best describes the lattice structure of ionic compounds?

Accepted Answer

A repeating pattern of positive and negative ions held together by electrostatic forces.

Question 14

Which of the following is a real-world application of ionic compounds?

Accepted Answer

Table salt used in food preservation

Question 15

A patient is given a saline solution intravenously. What is the main component of this solution?

Accepted Answer

$$\mathrm{NaCl}$$
