The ball will drop . Because xenon is denser than air . This can be shown by the fact xenon has a relative molecular mass of 131.29 , while air usually has a density of about 14.4 .
So , air is much less dense than xenon , therefore , the ballon will fall to the ground .
Hope I can help you ~

better to say relative molecular mass of air is about 14.4
