Density is g/cm^3 so you get the volume of the block:
4.6×5.5×8.4= 212.52cm^3
Then you take grams÷cm^3:
Carbon can form four covalent bonds. Covalent bonds are chemical bonds that form between nonmetals. In a covalent bond, two atoms share a pair of electrons. By forming four covalent bonds, carbon shares four pairs of electrons, thus filling its outer energy level and achieving stability.
Answer:
If we're talking about a neutral Silicon atom, 14 electrons, since it has 14 protons.
