Atomic Mass and Atomic Number

The atomic number of the element Silicon is 14.

The atomic mass of the element Silicon is 28.

Number of Subatomic Particles

The number of protons, neutrons and electrons in the element silicon is 14.

How to find Subatomic Particles

If the element is stable then the number of protons and electrons will be the same as the atomic number.And if the element is not stable the number of electrons will be different, but the number of protons will remain the same as the atomic number.

To find the number neutrons all you have to do is round the atomic mass and subtract that from the atomic number.
