The technique here is to balance the number of particles which is the numerator and the number of protons which is the denominator
Therefore
NUMERATOR:
257 – 4 = 253
DENOMINATOR:
100 – 2 = 98
the number of protons of an ion is simply its atomic number therefore, from the periodic table
98 = Californium
The answer here is that we will add an Isotope of californium, 253/98 Cf
