Question doesn't really make sense. There's no bike that's made out of chrome.
You can have a steel bike that is chromed on the surface. Or you can have a steel bike made out of an alloy containing chrome. Chrome-Molybdenum, Cr-Mo is a common, strong steel alloy. And it can be chromed.
What'll decide the weight of a bike isn't as much the material, as what the bike is intended to be used for, and what it's allowed to cost. An expensive race bike will be light. A cheap department store bike will be heavy.
Steel, aluminum, rubber and plastics
The BMX bikes that you buy at Target and or Walmart are not the same BMX bikes that are used in BMX Racing and BMX Freestyle. Real BMX bikes are lighter, they have diiferent size sprockets among many other things. Feel free to google the National Bicycle League or the American Bicycle League to get more information.
