Question 1: Which type of bond forms when electrons are shared between atoms?

Answer: Covalent bond

Question 2: True or False: Ionic bonds typically form between metals and non-metals.

Answer: True

Question 3: Complete the following sentence: In a metallic bond, electrons are shared in a ______.

Answer: sea

Question 4: Which of the following is a property of substances with covalent bonds?

Answer: Low melting and boiling points

Question 5: Explain why ionic compounds have high melting points.

Answer: Ionic compounds have high melting points due to the strong electrostatic forces between their ions, which require a lot of energy to break.

Question 6: Match the following terms to their definitions:

Answer: See full answer key

Question 7: Describe the process of formation for an ionic bond.

Answer: An ionic bond is formed when one atom donates an electron to another, resulting in the formation of a positively charged ion and a negatively charged ion. These oppositely charged ions attract each other, forming a strong electrostatic bond.

Question 8: Order the following steps in the formation of a covalent bond:

Question 9: What is the formula for calculating the number of moles?

Answer: Moles = mass (g) / molar mass (g/mol)

Question 10: True or False: Covalent bonds can conduct electricity.

Answer: False

Question 11: Describe how a metal lattice structure affects its properties.

Answer: The metal lattice allows electrons to move freely, which contributes to metals being good conductors of electricity and heat.

Question 12: Multiple choice question: Which element is most likely to form a covalent bond with chlorine?

Answer: Carbon
