How do isotopes work
The existence of isotopes was first suggested in 1913 by the radiochemist Frederick Soddy, based on studies of radioactive decay chains that indicated about 40 different species referred to as radioelements (i.e. radioactive elements) between uranium and lead, although the periodic table only allowed for 11 elements between lead and uranium inclusive. WebIf each isotope was in equal proportions (eg. each made up 50%) that would work, but that isn't the case here. One isotope makes up ~99% of all carbon, the other makes up ~1%. Clearly the isotope that makes up 99% needs to be given more importance. There is more than one way to take an average.

Stage 2: Acceleration: The ions are accelerated so that they all have the same kinetic energy. Stage 3: Deflection: The ions are then deflected by a magnetic field according to their masses. The lighter they are, the more they are deflected.
