Question

*Magnesium Oxide: MgO :: Aluminum Oxide: ______*

1️⃣ AlO
2️⃣ Al₂O₂
3️⃣ Al₃O₂
4️⃣ Al₂O₃​

Answer 1

Answer:

Magnesium Oxide: MgO :: Aluminium Oxide: Al2O3

Answer 2

Answer: MgO and  $Al_{2}$$O_{3}$

Explanation:

using Octet Rule

magnesium has valency +2 and oxygen has -2.magnesium can donate  two electrons whereas oxygen can take 2 electrons to complete their octet. and forms magnesium oxide(MgO).

similarly,

Aluminium(Al) has valency +3 while the oxygen has a valency -2.hence both can make bond by sharing of electron and can form aluminium oxide  ($Al_{2}$$O_{3}$).

therefore,

option (4) $Al_{2}$$O_{3}$ is correct.
