Frozen pipes

This one is for you brainiacs who know all there is about closing a house for the winter months: Assuming that you have done almost everything possible to prevent a disaster in freezing weather, including draining the pipes, etc….if the house is on a slab, which makes emptying the hot water heater completely almost impossible,
my husband claims that the water heater would still contain some water. If that is so, and it’s a 50 gallon tank and there’s 10 to 20 gallons left in the tank, if there should be a freeze (power failure plus generator failure), wouldn’t the water, as it begins to freeze, merely expand to fill the available space in the tank and not result in a disaster?
This has been driving me nuts!
TIA for any useful advice.
