What atomic mass is equivalent to seven helium nuclei?
What atomic number is equivalent to seven helium nuclei?
Now subtract that from the atomic mass and number of ununhexium
suppose the isotope of ununhexium ( find the symbol for this as well) undergoes a succession of seven a-decay reactions. What isotope would be the final product of these changes. I must show how I arrived at this answer
