Question 1:

Which of the following statements is true about ionic bonds?

Explanation: Ionic bonds involve the transfer of electrons from one atom to another, resulting in the formation of electrostatic attractions between positively and negatively charged ions.

Question 2:

Which of the following compounds is an example of an ionic compound?

Explanation: Sodium chloride (NaCl) is an example of an ionic compound. It consists of positively charged sodium ions (Na+) and negatively charged chloride ions (Cl-), held together by ionic bonds.

Question 3:

Which of the following elements tends to form positively charged ions in ionic compounds?

Explanation: Sodium (Na) tends to form positively charged ions (Na+) in ionic compounds. It readily loses one electron to achieve a stable electron configuration.

Question 4:

What is the typical arrangement of ions in a crystal lattice of an ionic compound?

Explanation: The typical arrangement of ions in a crystal lattice of an ionic compound is regular and repeating. The positive and negative ions are arranged in a specific pattern to maximize the electrostatic interactions.

Question 5:

Which of the following properties is typically associated with ionic compounds?

Explanation: Ionic compounds typically have high electrical conductivity in the molten or aqueous state, but low electrical conductivity in the solid state. They have high melting and boiling points, are brittle, and often dissolve well in water.
