Question

Which is the correct name of a compound that is formed by Si and O? silicon dioxide, silicon trioxygen, disilicon dioxygen, monosilicon oxide

Answer 1

Answer: Option (a) is the correct answer.

Step-by-step explanation:

Silicon is a non-metal and it shows oxidation state of +4 or -4. This is because it can either gain 4 electrons or lose 4 electrons.

Whereas oxidation state of oxygen atom when it combines with silicon is -2.

Therefore, when silicon combines with oxygen atom then charge on silicon is +4 and charge on oxygen atom is -2. So, it results into the formation of
`SiO_(2)`.

Hence, the reaction will be as follows.

`Si + O_(2) \rightarrow SiO_(2)`

Thus, we can conclude that correct name of the compound
`SiO_(2)` is silicon dioxide.
