The answer is SiO2
Since silicon has four valence electrons and each oxygen has 2, for every 1 silicon there must be 2 oxygen to fill in both element's outer shells satisfactorily. An alternative way to figure out the chemical formula is to simply swap the charges.
Silicon is a -4 and oxygen is a -2.
Oxygen's charge is brought down into subscript and set as the number of silicons in the chemical formula, making silicon Si2. Silicon's charge is brought down to make the number of oxygens in the chemical formula O4. The formula we have currently is Si2O4. Simplify it to get the empirical formula (divide by 2) and you get SiO2.

Answer:

SiO2 is formed

Explanation:

According to the question, the reaction is carried out between one atom of silicon which is represented symbolically as Si and two atom of oxygen which is represented as O2(oxygen exist as a molecule).

Computing the reactant from the question will be as follow ;

Si + O2 → SiO2

The combination of a single silicon atom and diatomic oxygen will produce silicon(iv)oxide.(SiO2).

The valence electron of the Si atom is 4∧+ . silicon will act more like a positive ion because it is bonded to a strongly negative ion. Oxygen been negatively charge(2∧-) will be the receiver.

The chemical formula of the compound can be calculated from the valence electron.

4∧+ : 2∧-

dividing both sides by 2 you will get

2 : 1

The 2 will be sub-scripted on the Oxygen atom to form SiO2.
