Answer:
In chemical nomenclature, the IUPAC nomenclature of organic chemistry is a systematic method of naming organic chemical compounds as recommended by the International Union of Pure and Applied Chemistry (IUPAC). ... IUPAC names can sometimes be simpler than older names, as with ethanol, instead of ethyl alcohol.

Explanation:
Formula to calculate how many particles are left is as follows.
N = 
where, 
= number of initial particles
l = number of half lives
As it is given that number of initial particles is 
and number of half-lives is 3.
Hence, putting the given values into the above equation as follows.
N = 
= 
= 
or, 
Thus, we can conclude that particles of radioactive nuclei remain in the given sample.
In five hours we've gone through 5 half lives so the answer is:
particles
