Respuesta :

the missing isotope in the equation is going to have the atomic mass and atomic number as the difference between the numbers of the other isotopes mass and atomic number respectively.
atomic mass 210-206= 4
atomic number 84-82= 2
the symbol has to correspond to the element with the atomic number. In this case 2 = He
