<u>Explanation:</u>
Consisting of boron (B), aluminum (Al), gallium (Ga), indium (In) and thallium (Tl) mainly int the boron group are the chemical elements in group 13 of the periodic table.
- The oxidation state (O.S) +1 or +2 of boron and aluminium is capable of forming stable compounds, gallium is supportive for O.S +1, +2 and +3. Indium is similar to gallium but its +1 compounds are more stable than others and thallium having maximum strength of the inert-pair effect and stable in the oxidation state of +1.
- Aluminium showcase such properties like silver colored, shiny and forms +1 and +2 ions and bright red compound with sulfur.
