Question

What type of oxide would Eka-Aluminium(Gallium) form?

• A. $Ga{O}_3$
• B. $G{a}_3{O}_2$
• C. $G{a}_2{O}_3$
• D. $GaO$

Answer 1

The correct option is C $G{a}_2{O}_3$

Eka-aluminium (Gallium) would form the oxide $G{a}_2{O}_3$.
Ga has 3 valence electrons and $O$ has 6 valence electrons. Ga shows a $+3$ oxidation state and $O$ shows $-2$ oxidation state. So, 2 Ga atoms will share 6 electrons and $3-O$ atoms will share 6 electrons to form $G{a}_2{O}_3$.
