Q: Which of the following p-block elements is known for forming stable +3 oxidation state compounds?

Solution: Aluminum commonly forms stable +3 oxidation state compounds.

Steps: 7

Step 1: Understand what p-block elements are. They are elements found in groups 13 to 18 of the periodic table.
Step 2: Identify the elements in group 13, which includes Aluminum (Al), Gallium (Ga), Indium (In), and Thallium (Tl).
Step 3: Learn about oxidation states. An oxidation state is a number that represents the total number of electrons an atom gains or loses to form a chemical bond.
Step 4: Focus on the +3 oxidation state. This means the element loses three electrons.
Step 5: Research which of the group 13 elements commonly forms stable +3 oxidation state compounds.
Step 6: Find that Aluminum (Al) is well-known for forming stable +3 oxidation state compounds, such as Aluminum oxide (Al2O3).
Step 7: Conclude that Aluminum is the answer to the question.
