The visible universe is estimated to contain between 1078 and 1080 atoms.

(One estimate at the higher end of the range is 4 x 1079.)

This is the estimated number of atoms in the observable universe, but since we do not know the absolute size of the universe, we cannot be certain.

(Most of the matter in the universe is still hydrogen.)

Be sure, we are not atoms; but as all the universe, we are made from many atoms !!

The number of atoms in the observable universe is somewhere in the vicinity of 1080. We can't even really estimate the number of atoms outside the observable universe ... it could be zero, or it could be infinite, and we have no real way of knowing which.

The number of atoms in the universe is estimated at 1078 to 1082. So the number of molecules would be smaller than this, obviously. Reference: http://www.universetoday.com/36302/atoms-in-the-universe/
