Calculating Protons in Isotopes of Elements

Question

The following refers to element Y
FORM 2 Chemistry
Given that isotope C contains 31 neutrons in its nucleus find the number of protons in isotope B

Answer

Number of electrons of C = 57-31 = 26
Number of electrons of B is the same as for C = No. of Protons
B = 26 protons
