Silicon is a group 4 semiconductor, which typically makes 4 bonds with other atoms, and forms many compounds that are similar to those of carbon, which is in the same group. It has an atomic number, Z = 14, and a mass number, A = 28. So, it has 14 protons, an equal number of electrons, and a neutron number, N = 14 (A - Z). read more
