Answer 1

Answer:

$\boxed {\boxed {\sf Ionic \ bond}}$

Explanation:

First, let's look at the Periodic Table.

We see that aluminum is a metal, while oxygen is a non-metal.

Now, let's recall three types of bonds

• Ionic: typically forms between a metal and a non-metal
• Covalent: usually forms between non-metals
• Metallic: tends to form with metals

Since we have a metal (Al) and a non-metal (O), aluminum oxide must have an ionic bond.
