There is no such thing as SicI4 in chemistry.
However, SiCl4 (with a capital C and a lowercase L) is silicon tertrachloride.
The value of N in silicon tetrachloride (SiCl4) is 4. This indicates that there are 4 chlorine atoms bonded to the central silicon atom in the molecule.
SiCl4 is silicon tetrachloride. I think the question has typo as SiCI4 does not exist.
Yes, SiCl4 forms ionic bonds. Silicon (Si) is a metalloid that can exhibit both covalent and ionic bonding. In SiCl4, silicon forms ionic bonds with chlorine (Cl) due to the large electronegativity difference between the two elements.
