Silicon is a non metal element. Atomic Mass of it is 28.
Number of neutrons = Mass number - atomic number = 29 - 14 = 15
Silicon is a non meta element. Atomic number of it is 19.
Atomic no.=no. of protons Atomic mass=no. of protons+no. of neutrons Hence, atomic mass is greater
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
