One atom of silicon is perfectly combined with the $\boxed{{\text{two atoms of oxygen}}}$ and forms silicon dioxide.

Further explanation:

Law of multiple proportions:

This law states that the molecule is a particle that is made up of two or more element. The elements are always combined in a ratio of fixed whole number.

Silicon has electron configuration $\left[{{\text{Ne}}}\right]3{s^2}3{p^2}$ so it can form 4 covalent bonds with other atoms.

One atom of silicon is combined with hydrogen in 1:4 ratio and form ${\text{Si}}{{\text{H}}_4}$ . This compound is known as silane. Thus silicon is not able to combine with three hydrogen atoms.

One atom of silicon is combined with calcium as calcium silicate $\left({{\text{C}}{{\text{a}}_{\text{2}}}{\text{Si}}{{\text{O}}_{\text{4}}}}\right)$ and Calcium silicon $\left({{\text{Ca}}{{\text{H}}_{\text{4}}}{\text{Si}}}\right)$ . Therefore, silicon would not be able to combine with 4 calcium simultaneously.

One atom of silicon is combined with oxygen in 1:2 ratio and form ${\text{Si}}{{\text{O}}_2}$ . This compound is known as silicon dioxide. Thus silicon can combine with two oxygen atoms.

One atom of silicon is combined with chlorine in 1:4 ratio and form ${\text{SiC}}{{\text{l}}_4}$ . This compound is known as silicon tetrachloride. Thus silicon is not able to combine with one chlorine.
