This is because carbon and silicon belong to the same group of elements on the periodic table known as Group 14, or the carbon group. Elements within the same group typically share similar chemical properties due to having the same number of valence electrons.
Carbon and silicon both have four valence electrons and tend to form covalent bonds with other atoms. They can form stable single, double, and triple bonds with other atoms, allowing them to participate in a wide range of chemical reactions. Carbon and silicon both exhibit allotropy, meaning they can exist in different structural forms such as diamond, graphite, and graphene for carbon, and crystalline and amorphous forms for silicon.
