The correct chemical formula for silane is **SiH4**.
Silicon (Si) has four valence electrons and can form four covalent bonds. Each hydrogen (H) atom has one valence electron and can form one bond. Therefore, four hydrogen atoms can bond with one silicon atom to satisfy the bonding requirements of silicon, resulting in the formula SiH4.
