Here's why:
* Carbon: Carbon has an atomic number of 6, meaning it has 6 electrons. Its electron configuration is 1s²2s²2p². This gives it 4 valence electrons (the electrons in the outermost shell) that are available for bonding.
* Silicon: Silicon has an atomic number of 14, with an electron configuration of 1s²2s²2p⁶3s²3p². It also has 4 valence electrons in its outermost shell.
Both carbon and silicon are in Group 14 (IVA) of the periodic table, and they are known for their ability to form four covalent bonds due to having four valence electrons. This property is fundamental to their role in organic chemistry and the formation of many inorganic compounds.
