The image shows a representative sample of 50 atoms of a fictious element, called lemonium ( Le ). Lemonium consists of three isotopes. The red spheres are Le – 19 , the light blue spheres are Le – 17 , and the dark blue spheres are Le – 15 . Determine the percent natural abundance of each of the three isotopes.
