Questions & Step-by-Step Solutions
What is the common oxidation state of aluminum in its compounds? (2020)
Step 1: Understand what oxidation state means. It is the charge of an atom in a compound.
Step 2: Look at aluminum (Al) in the periodic table. It is a metal.
Step 3: Metals often lose electrons to form positive charges.
Step 4: Aluminum typically loses 3 electrons when it forms compounds.
Step 5: Therefore, the common oxidation state of aluminum in its compounds is +3.
Oxidation State – The oxidation state of an element in a compound indicates the degree of oxidation (loss of electrons) of that element.
Aluminum Compounds – Aluminum typically forms compounds where it has a +3 oxidation state, such as in aluminum oxide (Al2O3) and aluminum chloride (AlCl3).
