What is the common oxidation state of Group 13 elements? (2021)

Step 1: Identify Group 13 elements. These include boron (B), aluminum (Al), gallium (Ga), indium (In), and thallium (Tl).
Step 2: Understand what oxidation state means. It refers to the charge of an atom after it has lost or gained electrons.
Step 3: Look at the electron configuration of Group 13 elements. They have three valence electrons in their outer shell.
Step 4: When these elements react, they tend to lose these three valence electrons.
Step 5: Losing three electrons results in a +3 charge, which is the oxidation state.
Step 6: Conclude that the common oxidation state for Group 13 elements is +3.
