Question 1: Which of the following is a type of chemical bond?

Answer: Ionic bond

Question 2: What is the primary difference between ionic and covalent bonds?

Answer: Ionic bonds involve transfer of electrons, covalent bonds involve sharing of electrons.

Question 3: Fill in the blank: A covalent bond is formed by the ______ of electrons between atoms.

Answer: sharing

Question 4: True or False: Atoms always form bonds to become stable.

Answer: True

Question 5: True or False: Covalent bonds form between metals and non-metals.

Answer: False

Question 6: Why do noble gases rarely form chemical bonds?

Answer: Noble gases rarely form chemical bonds because they have a full outer electron shell, making them stable.

Question 7: Explain how ionic bonds are formed.

Answer: Ionic bonds are formed when electrons are transferred from one atom to another, resulting in the formation of positively and negatively charged ions.

Question 8: Match the following terms to their definitions:

Question 10: Calculate the number of valence electrons in a chloride ion (Cl⁻). Use the formula: Valence electrons = Group number - Charge. Group number for Cl is 17.

Answer: 8

Question 11: Describe the properties of substances with covalent bonds and explain how these properties relate to the nature of covalent bonding.

Answer: Substances with covalent bonds generally have low melting and boiling points and do not conduct electricity in solid or liquid form. This is because covalent bonds involve the sharing of electrons, resulting in molecules rather than charged ions, contributing to weaker intermolecular forces.
