Why does the MgO have an ionic lattice structure?

Apparently, Magnesium Oxide has an ionic lattice structure. I understand why the bonds are ionic, but how was I supposed to know that MgO has a lattice structure? Is it because there are only 2 atoms in one molecule? How do I recognize a lattice structure by simply learning the name of the compound?

What do you think about this situation?

I have to say your side sounds much better. You sound like a very smart young woman and need to stick to your plan. If he loves you he will want you to finish school first and he should do the same. It is too easy to not go back or put if off longer if you take a break, and what if you enjoy your break a bit too much and end up getting pregnant. Then you would have to balance a child and going back to school. I could keep going on but I think you know what you should do. You have the rest of your lives to do new things. Good luck and think of the long term affects of what you decide. Remember if he loves you he will want what is best for you in the long run. Love needs to be patient.

How do I get rid of fleas in my Dad's House?

My elderly Dad lives by himself and cherishes the pets he has but they have created a bad situation. He had adopted my brothers kids one of who left a cat in a room plus mountains of clothes. Then on top of that there was flooding so he brought in outside cats to keep them safe and they were in the room for about a month. Now there is an unbelievable amount of fleas. He is on a fixed income. I am trying my best to kill them but it is hard to be in the room. Two minutes and you are covered in fleas. I have bombed, spread sevin garden dust and bombed again but with the mess of clothes I am sure they hide. But in order to be able to throw away the clothes the fleas need to be killed out some. please any ideas???? I know this sounds awful, but it is serious.
