One atom of silicon can properly be combined in a compound with
a. three atoms of hydrogen.
b. four atoms of calcium.
c. two atoms of oxygen.
d. one atom of chlorine.

Respuesta :

your answer is c. two atoms of oxygen.

One atom of silicon is perfectly combined with the [tex]\boxed{{\text{two atoms of oxygen}}}[/tex]  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 [tex]\left[{{\text{Ne}}}\right]3{s^2}3{p^2}[/tex]  so it can form 4 covalent bonds with other atoms.

One atom of silicon is combined with hydrogen in 1:4 ratio and form [tex]{\text{Si}}{{\text{H}}_4}[/tex] . 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 [tex]\left({{\text{C}}{{\text{a}}_{\text{2}}}{\text{Si}}{{\text{O}}_{\text{4}}}}\right)[/tex]   and Calcium silicon [tex]\left({{\text{Ca}}{{\text{H}}_{\text{4}}}{\text{Si}}}\right)[/tex] . 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 [tex]{\text{Si}}{{\text{O}}_2}[/tex] . 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 [tex]{\text{SiC}}{{\text{l}}_4}[/tex] . This compound is known as silicon tetrachloride. Thus silicon is not able to combine with one chlorine.
