Sb is the atomic symbol of antimony
S is the atomic symbol of sulfur
Si is the atomic symbol of silicon
The atomic number of Sb is 51
The atomic number of S is 16
The atomic number of Si is 14
The atomic mass of Sb is 121.76
The atomic mass of S is 32.06
The atomic mass of Si is 28.08
Thus the correct match will be
Sb B (antimony)
SA(32.06) (atomic mass)
SiC(14) (atomic number)
