Compare the structure and bonding of the three compounds:
• carbon dioxide
• magnesium oxide
• silicon dioxide.

Different bonds will form between two non-metals, compared to the bond formed between a metal and a non-metal. Think about which types of bond form between which types of element.

There are also multiple different types of structure; metallic and simple covalent to name a few. The type of bonding in a compound will go some way in determining the structure.

I hope this gave you some hints on where to start.

thanks! so is carbon dioxide covalently bonded, magnesium oxide ionically bonded and silicon dioxide covalently bonded?

That is correct in terms of bonding, but in terms of structure, carbon dioxide and silicon dioxide are actually two different types of covalent structure. Carbon dioxide is 'simple covalent' whereas silicon dioxide is 'giant covalent/macromolecular', like carbon allotropes such as diamond, graphite, etc.
If you haven't learnt about giant covalent structures then saying covalent for both should suffice, but if you have learnt about it then it is important to mention as the question asks for both structure and bonding.
